Plasma + Usability & Productivity Sprint in Valencia, Spain

The KDE Plasma and Usability teams recently converged on the beautiful Spanish city of Valencia for a combined development sprint. The teams admired Valencia's medieval architecture and stayed up until midnight eating sumptuous Mediterranean food. But of course, the real purpose was work!

We camped out in the offices of the Slimbook company, which were generously made available for the sprint. The aim was not only to hack on Plasma and the Usability & Productivity initiative, but also to benefit from the cross-pollination opportunities provided by hosting both sprints at the same time and place.

The result was a huge amount of work done on Plasma, KWin, Dolphin, Spectacle, and many other bits of KDE software.

Present for the Plasma sprint were Kai Uwe Broulik, David Edmundson, Nicolas Fella, Eike Hein, Roman Gilg, Aleix Pol Gonzalez, Marco Martin, and Bhushan Shah. They had quite a busy agenda:

  • Plasma 5.16's new notification system received a great deal of polish
  • Fixed a ton of bugs in the Plasma Browser Integration
  • Rewrote the widget positioning code for the desktop, making it much more robust, future-proof, and usable on touch:



  • Started work on making the Task Manager understand window stacking order, which will allow it to implement new interaction modes for grouped windows (e.g. bring forward the last-used window when clicked)
  • Worked on architecture improvements for the Task Manager to unify its different presentation modes and improve code robustness
  • Worked on a variety of architecture improvements for KWin to make it more future-proof, which, among other things, will improve multi-screen handling
  • Improved the user interface for the System Tray's settings window
  • Added calculator and unit conversion functionality to Kickoff and Application Dashboard

Kickoff now integrates a calculator and a unit conversion utility.

In addition to making technical progress, the Plasma and Usability teams got together to discuss a number of long-standing Plasma issues, and figure out how to resolve them:

We wanted to make it easier to test a custom-compiled version of Plasma. To do so, we implemented changes that allow you to integrate your custom-compiled Plasma into SDDM by running a single command, after which you can log into it normally. For more information, see this article.

We thought it would be a good idea to make more it obvious and discoverable that Plasma is made up of widgets, and show how they are configured. To do this, we decided to create a new "global edit mode" that's triggerable from within System Settings, as this is where new users generally expect everything to be configured. In this global edit mode, all widgets become visibly configurable, editable, removable, etc. We also want to make it easy to change the wallpaper in this mode. With all that done, we'll be able to remove the Desktop Toolbox as it currently exists.

There was a need to unify the disparate scaling methods, so we decided to visually connect the scale factor chooser with the "Force Fonts DPI" setting, since the former actually affects the latter, but not the other way around. This should make it clear that the scaling slider is the primary way to scale the screen, and the "force fonts DPI" control is nothing more than a way to tweak things further.

We needed Plasma to respect the system-wide scale factor on X11, so we came up with a path forward and a plan for getting it done!

We planned out how to add power actions to the lock screen. We concluded that not only does this make sense, but it will be necessary for Plasma Mobile anyway. In a multi-user environment, the user will have to enter an admin password to shut down or restart the machine when other users are also logged in.


Even during down time, KDE carries on coding!

Over in the Usability & Productivity room we had Méven Car, Albert Astals Cid, Noah Davis, Filip Fila, Nate Graham, and David Redondo. The agenda was similarly jam-packed, and included the following:

  • We ported Spectacle to use KGlobalAccel and away from KHotKeys, made the quit-after-copy feature finally work, and added support for drawing annotations on newly-taken screenshots
  • We implemented user-configurable sort ordering for wallpaper slideshows
  • Dolphin received human-readable sort order text and an auto-play-on-hover feature for media files
  • We added inline name feedback when creating new files or folders
  • Users can optionally close windows in the Present Windows effect with a middle-click
  • Many user interface improvements have been made to the Purpose framework, which implements sharing support in many apps (Dolphin, Spectacle, Okular, Gwenview as of recently, and so on)
  • We started working on improving the default selection of pictures available for user account avatars
  • Initial work has been done on a new "Recently used" feature for Dolphin and the file dialogs that will pull its data from a single consistent location and actually notice everything

We also came to some significant conclusions related to higher-level goals. For example, we plan to pay for professional user research to generate new "personas" and target user groups that represent the people using our software. We will use these personas as the basis for professional usability testing for Plasma, Dolphin, Gwenview, Okular, and other components of a basic desktop.

Additionally, we discussed how we can add release notes data to our apps' AppStream data, so that it shows up in software center apps like Discover. The big blocker was getting the required translations added to the tarball. We've started a dialogue with AppStream maintainer Matthias Klumpp regarding a new feature to pull translations from a remote location, which would support our workflow. The conversation is proceeding nicely so far.

Finally, VDG member Noah Davis dug deep into Breeze to work on visual consistency improvements related to selection highlights. Given his growing familiarity with the code, he's well on his way to becoming the next Breeze maintainer!

All in all, it was a very productive week. KDE Plasma and apps are in a great place right now, and the team's effort to further improve things will reach you in upcoming versions, so stay tuned!

Nice work. Great energy around  the KDE ecosystem. The future looks bright and shiny!

Hello and thanks for your review! Happy to see that duplication of functionality is avoided in one ot the often used usage scenarios!

Further I would like to remark that the sprint notes to which you refer are not visible.

Perhaps it is an idea to have them visible (read-only) for users without an account and only editable for users with an account.

I am interested in those notes since they give a piece of the roadmap.

Thanks!

John
