We need to come up with some sort of Application User Interface contract paradigm. I, for one, am really getting tired of UIs changing constantly. Sure, the changes might bring minimal improvements, maybe even major improvements sometimes, but if it completely breaks my muscle memory, moves something so I can’t find it anymore, or otherwise forces me to relearn how to use the application, shouldn’t I, as a user, have some say in that?

In the old days, we could choose when to upgrade (often at a significant financial cost). Now, things change out from under us without any notice whatsoever, or maybe with an annoying tutorial that pops up at the most inconvenient time possible.
