Notify me when a file is unlocked by another collaborator
When a file is locked for editing by another user, on a case-by-case basis, I would like to be notified via email when that file is unlocked.
- a file-setting that always notifies me after a user unlocks a specific file or
- a one-off subscription to a file when it is locked that I can set that notifies me via email when that file is unlocked. After this one-off notice occurs, the subscription would be deleted.
