There should be an option in the preferences to disable this kind of notifications, otherwise an user can recive tenths of notifications from rollbacks only.

Thank you for your message. Have you experienced it?
Yes, today is pretty continuous. That's true that I am quite active, but receiving notifications when other users revert back to a version that I authored is distracting and not requested.
We should either have a way to disable these notifications, or change the summary wrote by ''undo'' and ''rollback'' in all the projects.
I think you are on that already reported case. Sorry for the inconvenance!
