@YvetteLans, I answer here to keep the related things in one place.

• Related: is it really needed to show the database abbreviation at the right side? Can imagine that it can be handy sometimes, but for our use cases it’s often not helpful (we have a lot of databases that starts with the same letter and thus have the same abbreviation). I think it looks cleaner if it’s not in your face.
• Would be really awesome if we can see the full database name(s in the future) if you hoover over the reference

I added this information to the Reference creation feature, and we will try to figure out something.
