If I start writing a comment, but decide “nah, not right now” and back out, my partially written comment is “saved as draft”.

If I go back to the comment, the partially written comment is “restored from draft”.

• Are drafts stored indefinitely?
• Is there a way to see all my current drafts?
• If I keep creating new drafts without ever finishing them, will my storage get full?
• Is there any way to delete drafts?
