Debugging tool idea: /-/permissions page which shows you the actor and lets you type in the strings for action, resource_type and resource_identifier - then shows you EVERY plugin hook that would have executed and what it would have said, plus when the chain would have terminated.

Bonus: if you're logged in as the root user (or a user that matches some kind of permission check, maybe a check for permissions_debug) you get to see a rolling log of the last 30 permission checks and what the results were across the whole of Datasette. This should make figuring out permissions policies a whole lot easier.
