final ticket for today, I promise :​D
This is something that's been annoying me for quite some time now:

Pressing return/enter does nothing while the cursor/selector is in a field. Instead it should go to "enter edit" button.
That is, the default behaviour of most text-forms on the internet, and also what happens while pressing enter while editing MusicBrainz.
This saves quite a lot of time, and is crucial for people who use keyboard to edit.
