I get that, FancyZones let's you use keyboard shortcuts to move windows into custom configured zones. Typically I split my screen into a 2 up on the left, single in the middle, and 2 up on the right and I can move apps into those zones with just the arrow keys.

The annoying part of any current Linux solution for me is I have to use the mouse and resize a window and move it into what would normally be a zone. I'd prefer to be able to never use a mouse and be able to move a window with shortcut keys into a predefined zone and size.
