I come from Ubuntu 16.04 + Unity, where key combinations like ctrl + alt + numpad-6 would snap the focused window to the right of the current screen, and make the window fill half of the screen horizontally.
Similarly ctrl + alt + numpad-3 would make it snap to the lower right corner.
In Ubuntu 17.04 with Gnome the numpad-6 shortcut only snaps the window to the (far right) edge of all screens. Is there away to get the Unity behavior to Gnome?
