i have some small changes to ahk tiling
in some cases (like my right monitor) i used 9 keys for 9 layouts (2 columns with 3 rows, 2 full columns, fullscreen)
with 2key moving i can get 18 possible outcomes with 6 keys
first key determines top left corner, second one bottom right.

oh and changes to wallpaper.
