As a User I want to be able to quickly triage a long list of threads to mark them for deletion.
Option 1 - make the Deletion icon a toggle -- would be light light grey outline if not turned on, or maybe hidden until hover. As a user, i can click on icon to turn on Temporary tag (subject to 24 hour deletion), and click again to remove Temporary tag.
Option 2 - not mutually exclusive. Use keyboard command to toggle on and off, perhaps "e" to mimick Archive in some email clients.
Option 3 - drag and drop threads onto tags. Use case: User is in Untagged list, drags each one to a category or to Temporary, working down the list.
- There could also be an entry <New Tag> so you drag the thread there and it pops up asking you for the new tag name
See above, but in general for fast triaging of a large number of threads.
