JFYI, you need to fix pipeline errors to proceed :) In particular:

• Rename commits (or better - merge them into one) according to the Conventional Commits spec
• Fix Linting and Formatting errors.

Since 2.0 is released, you will have to adopt your merge request accordingly. In particular, the configuration is now done in a separate KCM, so you'll have to write some UI code.

can i take over?

[gikari]

Yep.

[v3ss0n]

I will work on it tomorrow and make a separate PR.

I'd hope that now that the KCM is there, we'd also be able to have a default layout per screen (as an example I have an ultrawide screen where I use three columns, and a normal 16:9 where I want to use normal tiling)

Is there any progress on this? This is a really important feature to me.
