With the multiple tabs across the top of the UE for each of the SQL scipts, why not put a new UE tab at the bottom for each DB connection (where the old SQL tabs were)? Instead of just the single UE tab.
So you may be connected to Dev, Text, and Production at the same time, and in each session you may have 5-10 SQL Edits going, it would be nice to have them all separated by tabs at the bottom. Then maybe on the bottom tab, instead of just showing “Unified Editor”, put something like UE@Dev, UE@Test, UE@Prod or just the instance name. Then it would be easy to swithch back and forth and not get mixed up.
Just a suggestion.
