Thanks! My understanding is that the dev one should be in dependency-groups and split into docs and test. Any reason for not doing this?

Not really, I will change that.

From what I understand, dependency-groups is the newer standard and replace optional-dependencies.
So I used dependency-groups for gui too

This is not my understanding: https://pydevtools.com/handbook/explanation/what-are-optional-dependencies-and-dependency-groups/. Any resource for justifying this?

Ok I didn't get the differences, I will change this again

It would be good to document (in INSTALLATION.md and rtkshowgeometry page) and test before merging.
