Overall, this is a great app. Without getting overly granular, I have been generally happy with it since I bought it a week ago (it came in a bundle offered at MacWorld). I am eying PSE6, but would love to have an alternative for a number of reasons. This would do the trick except for one thing.
<p>
I just can't function without something roughly equivalent to the "History" palette in PS. I just can't. Only having one "Undo" is simply not an option. I urge the developers to add this feature soon. If they do, I will recommend this to my friends as an alternative to PSE6.
