I honestly think scrollable VM is the future of window management. It just make sense to arrange windows like that instead of cram multiple opened windows in a fixed area.
Plus I can drag windows to the top and see multiple layout options and arrange them however I want, even with 10+ windows open don't feel the need to complicate things further.
I know this will piss off i3/keyboard purists, but oh well.
Edit: I know i3 is super customizable and all the malarkey but I want to get shit done and not spend all day fiddling with my config. ( this is coming from a serial distro/WM hopper )
The only thing I couldn't find is a way to define the "new window tiling mode", i.e in i3 you open two windows with vertical tiling, then change the tiling mode to horizontal and open two more windows. Now you'll have one tall window to the right and three windows splitting the right part one below the other.
