As a result of a discussion in another thread a new suggestion surfaced. CC is able to delete every System Restore Point (SRP) except for the newest one. I would suggest that CC shows the size of each SRP, as well. That would help the user to make a decision whether he/she wants to get rid of that particular SRP.
Perhaps CC should allow the user to remove the oldest SRP only ? (when it's not the only remaining SRP.)
