Needs a lot of work.
I opened the app for the first time and it gave me the color scheme selections available and the individual color selection above that. Then above those two it was just a black screen. So, I’m not sure what that section of the app is for other than to look at some color themes since it doesn’t offer to save or copy the color info or even display them aside from the tiny little color bars. The only part I got use out of was the gradient little TV option on the far left.
