Indeed - Unusable now, stay away!

I can but concur (sadly) with other reviewers. This was a great app when it focused on doing what it was meant to do, namely offer a way to partly b&w color photos (actualy process is reverser - color photo is made b&w, and then you partly color it back). It was easy and fund and powerful. Now with the latest version, and lots of mission creep, the app is utterly unusable, with a spinning beach ball all the time even with relatively small image files. Don’t waste your time!
