I wrote part of this in my app review.
One thing that would make things a little easier to use is having the "?" As a toggle switch to turn on and off the labels. In learning this app I use the labels to learn what the icons represent Right now I have to hold the ? down to display labels and continue to hbld down the ?. I would rather tap once on the ? To turn on and tap once on the ? To turn off. I am not sure exactly how to make this interface more iPad like instead of PC like. Except that the icons are just to small for my eyes. That is one of the biggest issues I have with the interface.
