Mouse Tiler has the same problem as the other options: it replaces the KWin system.

I recently added a compact mode for user interfaces similar to Mouse Tiler or Kzones, for those who don’t want the overlay to take up the entire screen.

The fact is that they all follow the same pattern, replacing the KWin system, and I don’t think that’s the best option. In the end, conflicts will always arise because you’ll always be fixing incompatibility issues with two systems that are fighting each other.

I haven’t tried polonium, so I don’t know how it works. If you have any problems or questions, don’t hesitate to ask me

Fluid tile does not replace the KWin tiling system, just adds more auto-tiling features. Krohnkrite and Karousel replace the current KWin tiling system

Fluid tile works with KWin tile editor (Meta + T shortcut), this allows better integration with KWin without needing to create another tile editor as is the case in Krohnkite, additionally, you can use the shortcuts that come with KDE by default to move windows, and expands functionalities such as changing the tile layout with shortcuts, etc…

The idea is to adapt to the KWin tiling system, not replace it

Try it and let me know what you think
