I am giving elementary a new try and I cannot find a setting for tiling windows to the corners (splitting the left or right tile), not even to upper and bottom half of the screen (thus split the screen up/down).
Just right and left tile are present in settings:
There are some options in
gsettings present, but they are not followed:
That list in dconf looks odd. Dconf reflects some keybindings for windows set in System Settings > Keyboard > Windows (e.g. for minimize) but doesn't reflect others.
This is so trivial in other desktops, is it really absent?
