I have a 21:9 screen and I would like to have following default tiling behavior: 1 Window - full screen 2 Windows - each 50% of screen horizontal split 3 Windows - each 1/3 of screen horizontal split 4 Windows - 4th window splits vertically to right window

With dwindle I can manually drag the windows to this configuration, but there must be a way to achieve this without using the mouse.

Any help is appreciated!
