I hook splitDesk to key bindings for "super + {left, right, up, down}" to quickly position terminals and other screen clutter.

Thankyou Steve for publishing this gist 👍

I extended it to work with up to three monitors: https://github.com/kstenschke/xmchord/blob/master/bin/actions/utils/splitDesk.sh
My adaptation isn't the most beautiful or finished solution, but i thought you might be interested.

P.S: Please let me know in case you prefer not being attributed as original author, than i'd remove the comment and third party attribution within the README.md of the project i used the script in.

Cheers, Kay
