A bit unfortunate, that we have to duplicate the list of layouts, but this is the limitation of the current config system (will be improved with the in the future with the separate KCM (see #94)).

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.

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.
