Back button in stencils
 

Actually after long thinking I bought this app and I'm very happy with it.
There's one thing, though, that I can't figure out- if I choose pictures from stencils there seems to be no way to get back to other stencils, while browsing other stencil categories I can press the back button, here I can see none.
Am I doing something wrong?

I'm sorry for the inconvenience this is causing! This is a known issue; fortunately, it's one we've fixed internally, so you should see a fix for it in an forthcoming update.
