[Feature Request] real master-stack layout support

[hax2]

Describe the problem/motivation

often you'll have a main window that you'll want to stay the biggest while you work on other windows, you should be able to quickly change what the master window is as well, dividing the screen equally between windows is almost never the desired situation and while you can use scripts to simulate automatic layouts, those layouts break if you try to change the order of the windows

Describe the solution you'd like

automatic tiling with shortcuts for changing the master window, windows moving within a fixed stack instead of just freely moving about the screen creating new and unwanted layouts

Alternatives considered

switching to linux
