Dominik is a PhD student at the Control Theory and Robotics Lab, TU Darmstadt, as part of the Research Training Group GKMM (GRK1362). My research focuses on state estimation in distributed systems. As hobby, I contribute to the KDE project and work on the Kate application and editor component.

Kate’s TabBar gets Movable Tabs

With the next Applications 16.08 release, Kate5’s tabs will be movable with the mouse. This was a feature request for quite some time, which is now fixed.Kate5's Moving TabsFor the record, the animated gif was created with the following two commands:

  1. ffmpeg -f alsa -f x11grab -r 30 -s 680x385 -i :0.0+0,0 -threads 0 output%04d.png
  2. convert -delay 1/30 -loop 0 -layers OptimizeFrame -size 680x385 -fuzz 2% output*.png output.gif

Much more work is going on at the Randa spring currently held in Switzerland. Would be nice if you support us 😉

MiniMap Fine-Tuning

Kate also supports a minimap of the text contents instead of a classical scrollbar. To enable it, just go to

MiniMap Settings

Here at the Randa meeting, we just invested some time to bring this minimap more in line with the Breeze style. You can see the difference here: Note the scrollbar slider frame, the new version (right) is more distinct and in line with the rounded corners of the Breeze style.

This change will be in the KDE Frameworks 5.24 release. If you want to support the KDE Randa developer meeting, please click on the banner 🙂

Working on Kate in Randa

Right now, around 40 developers are working together on bringing KDE to other platforms in Randa (Switzerland) for an entire week.

So far, I just fixed some bugs, e.g.:

  • Kate: Correctly restore view config of all split views (commit, bug, review)
  • Kate: Sort Kate Session Menu alphabetically (commit, bug, review)
  • Kate: Avoid hidden view spaces on start (commit, bug, review)
  • Kate, KDevelop: Tab Switcher Plugin: Make sure the height fits all items (commit, bug)

Much more work is going on, especially also with bringing Kate to Mac OS, or making it work better on Windows. For instance, thanks to Kåre and David, renaming documents already works now, and soon the filesystem browser plugin will be available in the next Kate on Windows release 🙂

Breeze Dark Color Scheme

Just as quick info, with the next KDE Frameworks 5 release, namely KF5 version 5.23, the KTextEditor framework gains a Breeze Dark color scheme. The colors mostly stick to the Breeze color palette, with some minor changes, since KTextEditor needs more colors the the color palette itself ships. To use this color scheme, go to the config dialog and choose “Breeze Dark” in the Fonts & Colors config page. We hope this is useful – mandatory screenshot:
