First off, you have created an amazing app that I'm sure have helped a ton of Photo Booth owners out there! Now I have been playing with the app for a week now and truly make the switch over to your app but is missing a feature that I use often and I'm sure would benefit other users out there as well who run a Photo Booth on a computer and wanting to switch from using Live Booth entirely. It would be great to have a Mac/PC app or script similar to the one that Live Booth offered. I know you have comparisons on your site with Live Booth and I feel that this feature would truly outshine any other app out there like Live Booth, Simple Booth and other apps like it. I would even gladly pay for the separate script/app. Here is a reference to the suggestion/idea http://www.liveboothapp.com/livebooth-direct/

For Photo Booth owners that utilize a computer to store photos or utilize an app to "filterize" photos then send back to the iPad I feel this would be a seamless and great addition to your app. It would allow to connect to a wifi network if available or an ad-hoc type network where computer creates the wireless connection that the iPad connects to and transfers photos that way when there is no network available. It essentially watches a folder on the mac/pc and transfers photos back into your app in the gallery which can then be emailed and printed from the Wifibooth app.

Keep up the great work!
