For the life of me, being a paying customer for ~3yrs now, I don’t know how/why HubSpot hasn’t implemented this yet. As our usage grows, so does our forms, and keeping them active across the entirety of the account is (a) unacceptable, and (b) not easily manageable at this time, even with folders, but (c) deleting them, even with data export, is the worst of options -and really the only one available.
