The app is great. Thank you!
Whenever I shoot a time-lapse I always get a bird or two flying through my shot. They cause a big blotch to appear like some artifact on an analog film. iPhoto has a great tool for mending things like a black bird on a blue sky. You just apply the repair brush to the bird and bam! he's gone. It's a bit of a pain to isolate which photo out of a thousand the bird is in, find it in iPhoto, make and save the change, and the re-insert the new frame exactly where the old photo was.
So....how about some photo editing tools including a repair brush for individual frames.
