Automatic layout modes like Dwindle/Master/etc

Is it possible to add automatic layouts like hyprland's dwindle or master layouts? It would basically be a tree where new windows are added based on the currently active window (dwindle) or order added (master). I have an ultra wide and being able to have auto tiling that continues to split beyond the base layouts would be a nice feature.

The issue names no files or tests. Start by locating the existing layout-mode and window-placement code, then define how Dwindle and Master should update the layout tree and how the result should be verified on an ultrawide display.
