The new gesture popup is very helpful. There's a minor typo. When you do up/right, the text says "Toggle Fullscreen", suggesting that another up/right will bring it back to normal. In fact, the gesture should just say "Full Screen Mode" as a different gesture is required to return it to normal.
Second, I find accomplishing "add to favorites" impossible without consulting the documentation to remind myself of the gesture. Could it be simplified. Perhaps a circle?
