This patch fixes https://sourceforge.net/p/lxde/feature-requests/191/
Lubuntu has had keybindings for window tiling for over a year (since Lubuntu 13.04). They are the same as the keybindings found on MS Windows and are just as useful or more as the Shift+Alt+Left and Shift+Alt+Right keybindings for moving windows between workspaces. Could we please upstream the window tiling keybindings, and make this part of LXDE by default?
