The icons are simple/basic, but after all, its not supposed to be elaborate considering the use case is for App icons. I use it differently though, at least for now. I'm creating puzzle books with icon graphics using the black and white feature as I need the icons to pop when printed. The credit level is low as it some of the icons I wouldn't use due to looking too much like AI so those end up wasted. I do see in the thread though that the ability to stack codes is coming soon. :)
