Ask HN: HoyKeys for iPad - my new app

Hi, I've been doing some work recently on a new iPad app called HotKeys, it's a series of programmable shortcut buttons for any app. You can then share these key setups with friends. It's currently in review, I'd like to get some feedback from the community as to whether I've wasted my time or you think it's an ok idea.
