This week in Usability & Productivity, part 11

Check out what KDE contributors have been up to this week in the world of Usability & Productivity! The KDE Applications 18.04 feature freeze happened this week, so there was a burst of energy to get in some last-minute new features for core KDE apps, among other welcome changes:

This week in Discover, part 11

This week we landed a significant visual improvement for Discover: the app lists have been re-implemented using a new “cards” style in Kirigami. This was a lovely collaboration between Marco Martin, Aleix Pol, and myself. And best of all, this pretty “cards”-style list is also available to other Kirigami apps!

Guest post: The Importance of QA

Today we have a guest post from Buovjaga, our friendly local QA evangelist for LibreOffice, KDE, Inkscape, Firefox and Thunderbird. Without further ado, I’d like to present…

The Importance of QA

With this post I hope to convince you that a strong quality assurance team can do miraculous things for a free software project.

The spectrum of QA is wide, and reducing the skill requirements is particularly relevant for KDE’s onboarding initiative.

The critical phase of onboarding a new contributor is the first contact. Sometimes the new person does not know what they want to do. Often you do not have a clear picture of what skills they have. You need to act fast or they will lose interest and disappear! This is the moment where you should hand them snacks: a query of bugs that need to be confirmed or re-confirmed. This is the lowest threshold for them to step across and into being a contributor, because:

They do not need to learn version control
They do not need to learn the patch submission processes
They do not need to be wordsmiths
They do not need to know interface design or how to draw pretty pictures
They should not even need to know how to use the features they are testing, because a valid bug report includes clear steps on what to do!

QA is highly important in itself, but it is also a gateway drug. A simplified story of the evolution of a contributor might be as follows:

They work on something meaningful
They get familiar with the structure of the project
They discover their own potential and the multitude of things they can help with

Not only does this evolution flow naturally through the QA team, but the experienced members are in a unique position to speed it up. This is because QA in the course of its work typically has to ferret out information from all the other teams. This leads to QA

Knowing who the subject-matter experts are
Discovering weak points in the organisation
Helping the various teams stay in sync with each other

In this aspect QA is acting like neurotransmitters in the body of the project.

The most apparent beneficial effect of having a strong QA team is that the developers are not distracted by massive amounts of first-stage bug analysis.

Primitive development team working in the bug tracker without the luxury of a QA team

In QA, too many cooks do not spoil the broth. A large and diverse team is more effective than a small one when trying to keep up with a myriad of software and hardware configurations.
A large teams allows the freedom for members to level up their skills. The more experience on advanced triaging techniques the members have, the less work developers have to spend per bug fix.

There is a long road ahead for KDE to reach a healthy state regarding QA. Recruit contributors early and often. Aim for a feedback loop of recruiting, where even fresh contributors brainstorm to come up with ways to find new people.

I invite everyone to go through these articles and improve them:
https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging
https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging/Identifying_duplicates
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

I also recommend KDE to look into making it easy for QA to perform git bisects for pinpointing regressions. Perhaps this could be achieved by offering compressed repositories containing binary snapshots for every single commit in a project like LibreOffice does.

This week in Usability & Productivity, part 10

Christmas came early this week! Today’s Usability & Productivity status is jam-packed with awesome stuff that I think you’re all really gonna love.

There’s all the awesome work on Discover, but it doesn’t stop there:

New Features

Dolphin now helps you install Konsole if it’s not installed when you open the Terminal pane (KDE bug 371822, implemented in KDE Applications 18.04.0, authored by Roman Inflianskas):
Dolphin now lets you find a symlink’s target file or folder (KDE bug 215069, implemented in KDE Applications 18.04.0, authored by Roman Inflianskas):
Gwenview’s slideshow feature can now be controlled via any MPRIS-compatible playback controller, such as the Media Playback widget, KDE Connect, and laptop keyboards’ media keys (KDE Phabricator revision D10972, implemented in KDE Plasma 5.13.0 and KDE Applications 18.04.0, authored by Friedrich Kossebau). Read more about it here!
By default for new installations, windows can now be tiled to any edge of the screen using the Meta+arrow key shortcuts, and can be maximized and minimized with Meta+PageUp/PageDown (KDE Phabricator Revision D11377, implemented in KDE Plasma 5.13.0, authored by me, Nate Graham)

Bugfixes

Fixed a bug in Gwenview causing image view’s touchpad scrolling to be uncontrollably sensitive when the scroll behavior is set to “Browse” (KDE bug 388353, fixed in KDE Applications 18.04.0, authored by Huon Imberger)
Fixed a bug in Gwenview causing the “Disable History” feature to not work (KDE bugs 332853 and 391527, fixed in KDE Applications 18.04.0, authored by Peter Mühlenpfordt)
Fixed a bug in Plasma causing fonts to be rendered in an ugly and pixellated manner when using a non-integer scale factor (e.g. 1.3x) and PLASMA_USE_QT_SCALING=1 (KDE bugs 391691 and 384031, fixed in KDE Frameworks 5.45, authored by me, Nate Graham):

Plasma looking awesome with a 1.3x scale factor
Fixed a bug regarding how fonts were rendered in KDE software that uses QTQuickControls controls (such as all Kirigami apps, for example) that was causing text to appear slightly too light and wispy at non-HiDPI and integer HiDPI scale factors (KDE bug 391780, fixed in KDE Frameworks 5.45, authored by me, Nate Graham):

Top: before. Bottom: after!
Fixed a bug in Konsole causing custom tab titles to be reset when changing profile options (KDE bug 354403, fixed in KDE Applications 18.04.0, authored by Ahmad Samir)

UI polish & improvements

The notifications widget now has a visible button to clear notifications (KDE bug 386068, fixed in Plasma 5.13.0, authored by Christian Fuchs):
The Audio Volume widget now presents a simplified display for the common use cases of one input and one output device and no apps recording audio (KDE Phabricator revision D11166, fixed in KDE Plasma 5.13.0, Authored by me, Nate Graham)
Plasma Folder View (AKA desktop icons) now provides a little bit more horizontal space for file and folder names (KDE Phabricator revision D11358, fixed in KDE Plasma 5.13.0, authored by me, Nate Graham)
To present a cleaner UI, Konsole now defaults to only showing the tab bar when there are multiple tabs (KDE Phabricator revision D11258, fixed in Konsole 18.04.0, authored by Kai Uwe Broulik):

It looks even better still with a global menu or the menu in a titlebar button:
Gwenview’s middle-click-to-zoom feature now zooms into the mouse cursor’s position, rather then the center of the image (KDE bug 308335, fixed in KDE Applications 18.04.0, authored by Peter Mühlenpfordt)
Gwenview’s advanced crop settings are now always displayed in the same order (KDE bug 391758, fixed in KDE Applications 18.04.0, authored by Gregory Legrain)

Finally, A notorious and longstanding bug has been fixed! The bug was this: in KDE environments where KWallet had not been set up (such as live sessions and barebones/DIY-style distros like Arch), you would be prompted for your password twice when connecting to a password-protected wifi network. This turned out to be a bug not in KDE software, but rather in the upstream FreeDesktop networkmanager software. It’s now been fixed as of networkmanager 1.10.6. If your distro doesn’t have that yet, please ask them to update or backport the fix.

Pretty awesome stuff, huh? Well there’s even more coming! We’re committed to making KDE Plasma the finest computing environment on planet earth, and I hope this kind of progress demonstrates the depth of that commitment. Want to hop on board and become a part of something big? Consider becoming a KDE contributor, particularly in development!

On the Updates page, the selection text can no longer overlap with the Update button (KDE bug 391632, fixed in KDE Plasma 5.13.0, authored by me, Nate Graham):
Increased the width of the “Add Source” dialog, so the URL is less likely to get cut off (KDE Phabricator revision D11219, fixed in KDE Plasma 5.13, authored by me, Nate Graham):
Discover now uses a more intuitive and obvious UI for choosing which source to install an app from (KDE bug 390464, fixed in KDE Plasma 5.13, authored by Aleix Pol):

(We’re aware of the visual papercuts in the above screenshot, and will be working to resolve them in the coming days and weeks)
Improved the app page by removing the redundant second copy of the app’s name (KDE Phabricator revision D11364, fixed in KDE Plasma 5.13.0, authored by me, Nate Graham) and fixed the top padding (KDE Phabricator revision D11362, fixed in KDE Frameworks 5.45, authored by me, Nate Graham):
Discover now shows a more obvious and less transient page when asked to open an invalid appstream://URL (KDE bug 391756, fixed in KDE Plasma 5.13, authored by Aleix Pol):

This week in Discover, part 8

This was a week of polish and preparation for Discover. We’ve got some nice new features in the pipeline but we’re not quite ready to announce them just yet. One is implemented but needs more polish, and another is under construction. I think you’ll like ’em once they’re ready! But in the meantime, here are some bugfixes and polish work:

Bugfixes

Fixed a bug causing Discover to emit scary “unmet dependency” warnings while browsing apps on certain systems (KDE bug 391142, fixed in KDE Plasma 5.12.3, authored by Aleix Pol)
Fixed a bug causing the back and forward arrow to appear in the screenshot pop-up before the screenshot was loaded (KDE bug 391130, fixed in KDE Plasma 5.12.3, authored by Aleix pol)
Fixed a bug causing apps from Flathub to not appear when clicking on the Flathub repo on Discover’s Settings page (KDE bug 391126, 5.12.3, authored by Aleix Pol)
Fixed a bug causing review headers for addons to appear malformed (KDE bug 391189, fixed in Plasma 5.12.3, authored by Aleix Pol)

UI Improvements and polish

Discover and other Kirigami apps now correctly use radio buttons for mutually exclusive actions (KDE bug 391144, fixed in KDE Plasma 5.13 and KDE Frameworks 5.44, authored by Aleix Pol)

Want to see faster progress on Discover? Help us out! KDE has great software and a strong focus on usability, productivity, and user satisfaction. But we’re short in the manpower department. There are lots of other ways to contribute, too!

Polishing Gwenview

Gwenview is a core KDE app, and an important tentpole of the Usability & Productivity initiative.

However, a few months ago Gwenview had no maintainer and few contributions. It was still a jewel, but was starting to bit-rot. Fast-forward to today: a lively crew of interested contributors are improving it daily, fixing bugs and resolving UI papercuts. Check out the Gwenview Phabricator project; it’s a hotbed of activity!

Gwenview highlights the value of joining a community over going your own way. Apps developed by a single person are vulnerable to dying when that person leaves the project, but apps with many developers can outlive the loss of any individual contributor.

Before starting a new project all by yourself, please consider joining an existing project whose design vision you can live with–it will be far more likely to outlive your interest in it. KDE offers a rich assortment of mature and popular cross-platform software already in use by people all over the world, so there are a lot of great options here!

Anyway, the new Gwenview team has been hard at work knocking out polish and fit-and-finish papercuts and adding new features. Here’s an assortment of what they’ve been up to recently:

New Features

Gwenview now has a “Fill” feature that will make the image always fill the entire viewport (KDE bug 195579, implemented in KDE Applications 18.04.0, authored by Silas Lenz)

Bugfixes

Fixed a bug where the upper selection handles could become inaccessible iun full screen mode (KDE Phabricator revision D10876, fixed in KDE Applications 17.12.3, authored by Henrik Fehlauer)
Fixed a bug that caused SVG images to not be scaled up when “Enlarge smaller images” is set in Gwenview’s Configure window (KDE bug 364822, fixed in KDE Applications 17.12.3, authored by Henrik Fehlauer):

UI improvements & polish

Back and forward icons are now more appropriate, and all the buttons in the Save confirmation window now have icons (KDE Phabricator revision D10847, fixed in KDE Applications 18.04.0, authored by Andrew Crouthamel):
Replaced a few uses of -symbolic icons with regular ones, for better compatibility with non-Breeze icon themes (KDE Phabricator revision D10843, fixed in KDE Applications 17.12.3, authored by Andrew Crouthamel)
Selection and accent colors in full screen mode now match the system color scheme (KDE Phabricator revision D10649, fixed in KDE Applications 18.04.0, authored by Huon Imberger):
The Crop and Red Eye Removal toolbars now look right in full screen mode (KDE Phabricator revision D10763, fixed in KDE Applications 17.12.3, authored by Huon Imberger):
The thumbnail bar now remembers whether it was shown or hidden while in full screen mode (KDE Phabricator revision D10785, fixed in KDE Applications 17.12.3, authored by Huon Imberger)
Gwenview now starts in full screen mode if it was in full screen when last quit, like other KDE apps do (KDE bug 383093, fixed in KDE Applications 18.04.0, authored by Peter Mühlenpfordt)
The URL navigator now has consistent and appropriate margins in full screen mode (KDE Phabricator revision D10881 fixed in KDE Applications 17.12.3, authored by Huon Imberger)

There’s more on the way, too. One of the core KDE apps, Gwenview’s future is bright and getting brighter. Come check out the Phabricator project and join the Gwenview team!
