After some frustration with other text editors, I recently discovered jEdit. It seems like a light-weight editor that has so many plugins that it could be grown to be a full IDE. I especially like how it handles SQL. I've found quite a few people that happily converted from Emacs to jEdit. But have yet to find people that converted from an IDE.
I'm not trying to argue which is the best IDE. I just want to know if people are actively using jEdit as an IDE and how it compares to other IDE's they've used. I have been trying to get jEdit to be an IDE but it appears to take quite a bit of configuration and I'm concerned it will just be a waste of time.
