After I accidentally screwed up my system Friday night, I ended up with no choice but to install all system updates from KDE neon “unstable” which now defaults to a Plasma 6 session. I certainly wasn’t planning on spending a few hours that evening fixing my setup. Alas, I am now taking “eating your own dog food” to the extreme and made my daily driver laptop run Plasma 6.
After what felt like an eternity we were finally able to come together in Augsburg, Germany for the Plasma Sprint that was originally planned for April of 2020, kindly hosted by TUXEDO Computers in their offices. There were sixteen attendees from six countries and it was great to have three newcomers on board, too.
Depending on your calendar system, another year is coming to a close very soon. While this year was a lot more enjoyable for many of us than the last two, we surely didn’t expect things to go downhill even more for others. As I am looking forward to some days off with my family, let me take a step back and reflect on some of the things I did in KDE in the last twelve months.
A while ago Google announced a new API level for browser extensions, named Manifest v3. You might have heard it in the news that it will impact the ability for extensions to arbitrarily filter traffic. While this particular aspect does not affect Plasma Browser Integration, there’s still a large number of behavior and API changes that we need to adapt to, especially when it comes to tampering with a website’s content. It’s getting more urgent as Chrome will stop stop running extensions still using the old version 2 by the end of this year!
Luckily, most extension features, namely KDE Connect integration, tabs and history runner, and download monitoring could be ported quite easily. However, media controls and Share API integration needed a significant rewrite in order to work with the new restrictions imposed on us, notably it is no longer possible for an extension to inject arbitrary inline JavaScript into websites. Many thanks to Fabian Vogt for refactoring this part of the extension!
A KIO worker for accessing iOS devices through the Apple File Conduit service.
While there have been several projects like this for both KDE 4 and Frameworks 5, this one has been written on top of the latest KIO classes and will be officially part of the next KDE Gear release. It is now part of the kio-extras module, which also houses the Android counterpart for transferring files over the MTP protocol.

My tool of choice for analyzing performance issues is Hotspot, KDAB’s excellent perf visualizer. It comes with an easy to use GUI for browsing the results collected by it. Particularly its flame graph lets you quickly detect, well, hotspots during execution. Just launch an application through Hotspot or attach it to a running one and look at the graphs. Depending on your system configuration you might need to adjust the perf_event_paranoid kernel setting in order for it to inspect other processes.
I just returned from this year’s KDE Akademy in Barcelona. After two years of only virtual sprints it has been great to finally meet up with many fellow KDE friends, most of which I haven’t seen since 2019, and also get to know some of the faces of people that have joined in-between.
It’s been more than ten years since Dolphin, KDE’s versatile file manager, introduced its own custom QGraphicsView-based view engine. With that came more detailed view modes with grouping support, animated transitions, and a new places panel with sections. Unfortunately, it is all based on a now long-abandoned “Itemviews NG” project, and is inherently incompatible with Qt’s traditional model-view code used elsewhere in KDE.
A few weeks ago I sat down and over the course of a few evenings I ported Dolphin back to using the KFilePlacesView provided by KIO which is used in the Open and Save dialogs, among other places.

A fix is being worked on, but might take a bit, sorry about that.
Update [2021-10-25]: Due to issues with setting up the now-mandatory 2FA for logging into the Add-on page, we cannot address the issue at this time. Stay tuned…
Update [2021-10-27]: An updated version has been uploaded but it’s pending review…
Update [2021-10-29]: The update has been released, the extension is available again, in version 1.8.1 for Firefox.
In my 10 year anniversary blog post I mentioned how I wanted to fully redesign the icon chooser dialog which hasn’t changed since its inception and my childhood. Well, guess what I just did between sessions at this year’s Akademy.
I recently added a job creator test application to KJobWidgets so I could test the job tracker in Plasma’s notification center without having to write fake KJob classes all the time. The user interface for it was quickly bodged together in Qt Designer, so the other day I figured, I might as well try to recreate the new icon dialog layout and hook its existing C++ logic to a new UI.
