JBCoolCats review for PixPix Image Editor

I use PixPix for my Shopify store, but just the free version. It works good for the basic things. So far, I only have used it for removing text in the background and cropping. I would like it better if I could change the color of the brush using a color picking tool to take it easy to match exactly the background color. It integrates well into Shopify.
