@pitaj Having a branch for the production version with a similar dump output is actually a great idea. You can solve the conflicts during git merge (or PRs if there would be a tea working on this) and there should be no problem.
@pichalite I selected the 'Hidden' button and the group is completely hidden, but I want the group to be visible to the administrator and the users who are part of it.
I also want users to be hidden, but a specific user can only see users who are part of the same group with him. For these I need a new custom plugin, @julian?
