Working on my local dev blog, I just now realized something for the first time: There is (for security reasons, obviously) a login timeout, meaning if you click on a link in the backend after the timeout, a user is prompted with the login screen again. (Actually, I knew that already.)
Now, if the user logs in again, he's back on the start page of the admin backend. (That's the part I didn't actually realize before.)
I think it would be a huge improvement in terms of usability, if after the re-login, the user would be "forwarded back to where he was working before the timeout" (Hope you get what I mean here.), if that's possible with a reasonable effort of implementation. (Including the world-famous performance pennies, of course! )
