The ICS browser is the worst offender of this. If you enable Labs mode, the address bar disappears away and you need to gesture-swipe from the screen edge to get a semi-circular menu. Now, this in itself is a brilliant idea, only marred by the fact that it's a bunch of icons that you can't understand. I'd love if they added a big semi-transparent textbox on the top informing you which option is currently under your finger, something analogous to the alphabets that popup when you're scrubbing through the contact alphabet list.
