PhotoAppLink: Better photo editing on iOS
This looks really cool. PhotoAppLink is basically a framework developers can add to their apps to make editing of one photo easier. PhotoAppLink allows to pass a photo from one photo app to the other. Some great apps like Color Splash and AutoStitch support this already, and it has probably been around for some time too, but I hope this gets some momentum.
(Or maybe (hopefully?) Apple themselves solve the “multiple photos problem” on iOS.)
