Instructions/help/guide for people with overwhelming amount or too many rooms

[Mikaela]

I am once again running t3chguy's script to leave all Matrix rooms and thought that it would be nice if Riot or something handled this scenario and there were clear instructions on what to do when there are too many rooms for the user to handle. In IRC I would do /join 0 which is instant /part everywhere on most (if not all IRC servers).

I don't know how it would work, maybe a list of rooms with checkboxes of which I could select which to save, maybe per category (existing and meta*) so I could stay in favourites or direct chats and unspecified/meta categories like "only people who are invited can join" so I wouldn't need to ask people for invites again.
