The program is good, but there is still where to develop. For example, now it is not possible to select individual photos or it’s too much to deselect one-by-one from 10000 photos of my library, now it is not possible to select a specific folder with photos from which I want to make a collage. There is no possibility to clean the cache and the app takes an extra 500-800MB due to the photo cache is not cleanable. The "Rate this app" button does not work.
