People, roles & permissions — Grant access to a whole folder

The Folder access card sets one person's access to every table in a folder at once — Full, Read and create, Read only or No access. This is what replaced giving somebody a separate workspace, and unlike a separate workspace nothing they can see loses its relationships to the rest of your data. Access resolves in one order: an explicit override on the table wins; failing that the folder's grant applies; failing that their role decides. Marking the folder hidden removes it — and its name — from anyone without a grant.
