Gets the job done!

Coming over to the Mac from PC, I was looking for a photoshop solution, but didnt need something as extensive and expensive. This app has a feature similar to the magic brush that I needed. Basically removes all of the green...but I noticed it still left a small amount. I tried increasing the sensitivity, but it removed too much. I was able to do what I needed by removing the bulk of it with the green screen button and then manually editing with the brush. Decreased the brush size and increased the opacity for the small corners and it worked out pretty well. This app is simple in that it only supports 2 layers of photos, but it had everything I needed. Couldnt find anything else in the Mac App store that did this.
