Its getting better
There are nothing but good reviews of this product on iTunes. I was not prepared for how bad this software is. It keeps locking up. You cant drag and drop even one picture into the app, but have to go through a painful process to put them in by opening one photo at a time from the add-file dialog. There is MUCH room for improvement here, its not worth the money I spent.

After e-mailing Customer service, they have now fixed my two biggest issues (Ive tested it for them, and the latest version on their website has the fixes). They fixed the lock-up issue, and Ive now Successfully saved several panoramas (it used to lock-up during the save process). And now when I open several photo files in a single "file-open" operation, it imports them in order, so I no longer have to open them one-at-a-time. So Ive changed my rating from one to three stars.
Improvements I would like to see that would make me give it 5 stars:
1. Drag-n-drop from iPhoto.
2. auto cropping (largest rectangle possible withing the confines of the stitched panorama.)
