First off may I say how DBEdit 2 is such a fantastic, simple and easy piece of software. It does exactly what it says on the tin! Well done you!
I do have a some suggestions that could improve user usability:
* A default option in Connections - I have lost count how many times I've forgot to select the connection first!
* Tabbed Panes - History for scripts is great and useful but being able to switch between multiple scripts in the same instance would be even greater!
* Executing Status bar/ Progress bar instead of dialog box - It would be useful to able to execute multiple scripts without the dialog box disabling the whole program until that particular script finishes. It's stop me from opening multiple instances to run different heavy data laden scripts!
These are only suggestions but I do believe they would improve user usability and make DBEdit 2 even greater!
