i think it's dumb that when you add a photo from the camera roll to an album it leaves that photo in the camera roll too and if you delete it from the camera roll it deletes it from the album.
+1 on this one.
I rejoiced when I saw this feature and went through and moved all of the wallpapers I had saved from here into a new folder then went through my camera roll and cleared them all out.
No more saved wallpapers.
