it would be nice that IDEA recognizes branches of the same projects, so I can switch active branch of a project back and forth, view diffs and apply patches easily. It would be thing that regular developer need daily, not those memory eaters(endless wizards) added in each version.
It would be also a step toward supporting distributed VCS like mercurial. Don't now why we need archaic vcs support (ClearCase) in Selena. Does anybody use it?
