I want to like it-

I know it must be me. There are great reviews here but I am having a hard time figuring this app out- I mean I get the basics- sort of- but how do you save a pic to camera roll? All I can see are "open in" with list of apps. I went to settings and tried to turn on the guide but the slider wouldnt work- (none of the off sliders would)
Looks like a great app but I hesitate to purchase the whole shebang.

oh-mercy about Colorburn, v2.2.1
