You know, that actually makes a lot of sense. It wouldn't be a user group, per se, like "Registered Users" and "Administrators" are, but it's more cohesive than having a separate global checkbox like it is now. Good idea.
I have like 20 categories, for any change (or multiple) I have to scroll down a lot. Sounds lazy, but if there would be a save button on the top or, better, each category would have save (and "save all" on top and button) it will be much easier.
I agree. I think we could add a save button in each row. Even with 12 categories on a small screen it becomes a pain to go to the bottom to save.
