I'm giving this app 2 stars because it lacks the ability to mirror images. It gives you all those other options but not mirror? One of the most singlehandedly greatest functions by artists and for artists. But you say, hey why give it 2 stars for lacking just that fearure. BECAUSE IT IS SUCH A CRITICAL FEATURE. A photo can look 7/10 and you be meh, slightly disappointed, then you mirror it at it is 9.5/10!! Mirroring should be built into the app that browses your photo library! End of story.
