Been using a very similar (in idea) layout: https://eurkey.steffen.bruentjen.eu/
The main difference seems to be in positioning of different characters on a quick glance?
Same. Using EurKey exclusively on all my devices for the last six months. Writing code, German and English text and it’s great.
Yeah I like this layout and it seems to be available on all Linux distros. I only use it occasionally to talk to friends back home though, not sure how it is for constant use.
