Let me start by thanking you for the wonderful database front-end you built.
I do, however, have a few minor suggestions for improvement:
If I invoke the table autocomplete, all the matching tables from all databases are shown in a dropdown list. However, this list is limited in size, and it may well be that the matching tables in the active database are in the truncated end of the list. It would be nice if the matching tables from the active database would show up first in the list, as most of the work done in queries only takes place within a single database.
When dragging the table into the script editor, it includes the database name, even though I unchecked "Set full object names in editors" in the settings.
