Mine doesn't remove whitespace....
Resharper is amazing! Live code templates. Quick code generation and refactoring!
Older versions of Netbeans didn't change whitespace lines at all. The newer versions do for some reason. I haven't followed the NB community for quite a while now, so I don't know why that changed in version 5, but I find it annoying. Of course it could just be a simple checkbox option that I've neglected to change... =)
Good refactoring tools can be a life saver on some projects... especially the ones where the team lead has no idea what he/she really needs and sort of changes things mid-course.
