With some current, and perhaps future, operations it's possible to overwrite the list of unread messages you get when you log on to the UT. Currently, there is no way to get this list back - the fixed-time "Go back" options are only an approximation.

To the "Go back" function, could we add "Unread messages since last logon"? I suppose, if we're being precise, this should be unread messages since the last time the "New messages created during your session by doing a global refresh" button was manually clicked.

Or, if you're feeling ambitious (:)), perhaps both options:

"Unread messages since my last logon"
"Unread messages since my last global refresh"

To be even more precise, these should probably show messages created since those times, whether I've read them or not i.e.

"Messages created since my last logon"
"Messages created since my last global refresh"
