I am curious what others think about this feature ?
It would be nice if IJ could roll back --all-- of its configuration settings to a prior point.
Those files are already kept in the Local VCS so the information is there.
My main use case is when I imported a Maven module/project:
1) Either IJ wipes out or corrupts my other modules especially the Maven paths.
2) The Maven import takes hours either trying to resolve dependencies (Even with the latest EAP)
3) Name your own reason.
I realize IJ would probably have to restart, but that would still save so much time and frustration.
