Back button should go back where you exactly were
 

If you go into a menu from a second page, and you push the "up" button, you will and up on first page, not the second where you were. Very uncomfortable.

Example: Go to Status bar/Settings. For me, the Prefix is on the second page. I tap it. When I finish setting it, I tap "Up", to go back one level. And I will end up on the first page of the Status bar/Settings. Would be much better and more natural to arrive exactly to the same place where Prefix is.

I'm pretty sure there's a very, very, very old bug about that, but I can't actually find it ;D.

IIRC, it's not as easy as it might sound, because reasons.
