I think it would be very helpful if when the menu was activated within a video, the cursor was placed directly on the progress slider. 99 out of 100 times that's where people want to go and it would be a lot easier to use. Right now the cursor is centered between all the options so you always have to tilt your head after activating the menu.

(If this were an option that could be turned on an off in settings, that would obviously be just as good)
