I think I’ve mentioned this before (couldn’t find it by searching “Mass”), but I’d love a way to select multiple spaces to delete or hide.
Going through the process now to clean-up (hiding old spaces / deleting blank or barely used spaces) and it’s not too much fun…
ya that’s a chore for sure 
Right now i’m thinking that this kind of bulk list functionality might work best in the context of a separate dedicated user page, which would need to be made first
I would imagine the dedicated user page would have dashboard-like functionality. Like, a list of last x created spaces, last x modified. Last z created cards. Things like that to help you quickly find your spaces to work on, with extra stats and info that the current listings don’t afford
