Many times while I am coding on left monitor (perhaps a setup screen, or something that adds to a queue) I watch plsql developer in my right monitor refreshing a query every 2 seconds and if the new record appears then I know that it worked correctly otherwise I need to dig deeper into the code. With dbFordge I would constantly have to click the refresh button and if there were any parameters I'd have to see the parameter entry screen on each refresh. I use this feature regularly when tracking down bugs. It is a real convenience.
