This JBuilder feature was absolutely awesome. I used to worry about 
whether I saved a file or not because I didn't want to loose my ability 
to quickly undo experimental refactorings. However, as soon as I learned 
about the built in JBuilder versioning, I saved my files all the time.

You should absolutely have auto-save with a local history. This allows 
the developer to never loose any work: they never loose work in 
progress, but they also never loose work they've done in the past 
(within reason. Obviously you don't want to keep 3 years worth of diffs 
lying around by default).
