PixaFlux

Node-based editing is great! More apps should allow it...

It's by far the easiest image manipulation and composition tool, which I have ever used. The user interface is very simplistic and does not overwhelm you. It's node based, non-destructive workflow is outstanding and intuitive. You achieve complex compositions in no time compared to any layer based image processing tool, where you have to think twice, before you do a task. PixaFlux is open for any experiments, because of it's node based character. Just create and connect nodes how you like. If you don't like the result, throw the nodes away or put them aside and change the connections. That's more powerful than any undo/redo loop, because it's a non linear workflow. For me, PixaFlux shows, how the future of image processing and composition has to be.
