It's a useful feature and it seems to exist in raw Eclipse. I'm aware of the Source -> Override/Implement methods, but this is clunky when you could hover over an interface and hit Ctrl+1 and auto-implement all methods for that interface (which seems to be pretty much most use cases for me). At the moment the quick-fix only seems to have renaming options. Is there something wrong with my configuration?
If not, is there a way to make feature requests? :-))
