Not sure why I did not put those from start... Actually *not* having an undo point here can be problematic, since undoing some previous action was trying to restore from bad pointer (I think) in UI, generating asserts. Note however that it's not a 'pure' undo, in that you may not find your linked data in exact same state as before deleting it, after an undo, since it actually implies *reloading* the deleted libraries (and not restoring from a previously stored memory dump). Reported by @sergey, thanks.
