Currently, there doesn't seem to be a way to undo check-ins, or mass rollbacks.
Ideally, I'd like to be able to search for a check-in comment and rollback all (or selected) items to their respective previous versions.
At the least, it would be nice if I could get to the individual item histories from the search results when I search on check-in comments. Currently, the best I can do is just order them by filename so its easier to browse to them in the folder tree.
