I'm a little obsessive over having things dated and being able to be catalogue them thusly. While dates are shown in exported Assistant chats and Assistant can catalogue threads by "today, yesterday, last seven days", I'd like it if the exact dates were surfaced within the Assistant UI.
The date a thread was created should be shown in the tooltip when a thread is hovered over in the list, and each message in the chat should (optionally) have a user-configurable date format shown. Users should also be able to sort threads by date.
