My pet peeve about UI menus is how in Windows it has to start with "File".

Want to exit? File -> Exit. Oh, logical.

Why can't they be sane and called it "Program"? Want to change preferences? Program -> Preferences instead of going "if you want to change the preferences, you will be wanting to 'edit the preferences', so it's under Edit. Where Cut, Copy, Paste belong. Logical, no?"

Want to exit? Program -> Exit instead of File -> Exit.

Rant over.
