development in azulejo is going slow but steady. I fixed a few bugs and built a deb package so anyone can try it with minimal effort.
The default keymap looks like this:
Super+2 Place two windows side by side
Super+3 Place a window on the left half of the screen and two on the right half
Super+4 Arrange four windows two by two
Super+R Rotate windows' positions i.e. cycle windows
Super+H Resize and move current window to the left
Super+K Resize and move current window to the right
Super+Y Resize and move current window to left upper corner
Super+U Resize and move current window to right upper corner
Super+B Resize and move current window to left lower corner
Super+N Resize and move current window to right lower corner
I tried to make it as customizable as possible. You can redefine everything from keyboard shortcuts to window geometries.
As it is, it fulfills my needs, I'm using it everyday on openbox and sometimes on gnome. I wouldn't mind (it's fun) polishing it a bit more and add a couple of features if it gets a bit of a userbase.
