A bit sleazy...

For the user-configurable buttons, the screen shots show two full screens of 18 buttons each (36 total). I saw there was an in app purchase for buttons, but the screen shots lead you to believe you will get at least one screen (18 buttons). The app however only comes with 3 buttons! Not 36 or even 18! Based on this Im thinking I dont trust this developer in general.
