The problem, almost all the features are already available with the edit-feature starting with Ice Cream Sandwich.
Don't get me wrong. I lobe choice and new apps. But another app using memory for a feature that is already built -in. No big deal. But this app is from Google, as Google bought it. So where is the deal?
It even misses a feature. You can't even scribble or "doodle" on the photo. A feature to pixel or blur-out a part would also be nice. That is a problem with "edit", too. The doodle is always transparent. So how am I supposed to hide number-plates or faces in this paranoid world?
I get it. There are some few filters that the edit-feature misses. And the edit-feature from the firmware have at least 1 that can't be find in Snapseed right now (release 2012).
Edit - Integrated in Android since 4.0
