We often watch the news during dinner on our iPad using the Tablo app. Works great.
Because we are watching slightly time delayed - no automatic commercial skip - we often are using the advance button to skip commercials.
Having a keyboard key assigned to the advance 30 second function would be so helpful (we have a keyboard attached while watching).
Short of this, making the target area for the advance 30 second button bigger would help a lot. Reaching over to hit that often takes us (old and feeble folks!) a couple of tries.
