Homebrew Versioning

It would be great if the homebrew content creation suite was upgraded with the two following features, which would both serve to reduce community homebrew clutter and allow community members to get updates to their homebrew collection without having to manually search for new versions.

1. Live versioning: a single piece of homebrew content would be able to receive updates (rather than having to make a separate piece of content). When a user with a character using the outdated homebrew visited their sheet, a notification would pop up, detailing changes, newly created incompatibilities (e.g., if a spell's level was increased to a level for which the PC doesn't have a slot), etc., with the option to update the content or keep the old version and possibly update at a later point.
2. Dead content removal: if a piece of homebrew content is not being used by any community member, it would be able to be deleted or "unsubmitted" by its creator.
