I have an external 4K display on my laptop with plenty of space, that I usually use like four individual monitors in a grid. So I tend to put one window in every corner of the screen (IDE, terminal, browser, etc.). In Ubuntu 16.04, Unity offered to option to automatically place windows there by moving them to the screen edge or screen corner, so you had 8 options on where to put a window just by moving it around (top left corner, top half, top right corner, right half, etc.). Now in Ubuntu 18.04, only the Windows-like behaviour seems to be implemented with maximize (top edge), left half (left edge) and right half (right edge). Is there a way to get the additional areas back as in Unity?
Thanks!
Best regards, Philipp
After writing the question, a similar one popped up: Resize 4 windows to occupy the screen without overlap on Ubuntu 18.04
The keyword was "tiling" and the GNOME extension ShellTile does exactly what I was looking for.
GNOME Extension of preference for me is: Put Windows
It's supposed to be a replacement for the Unity functionality you mentioned.
Use ShellTIle
First enable extensions with: (the prefix chrome is not related to chromium, it works on any window)
Then go to ShellTIle
And click ON
Try gtile, window tiling suited for both landscape and portrait mode.
It has helpful shortcuts (Super+Alt+2, Super+Alt+8, etc) and presets (2x2 4k landscape mode, custom 1x2 portrait mode, etc).
