This would be very helpful for those like me who like to arrange their perfect breeding pokemon in their own boxes and tracks progress through how many slots are filled. I'm currently doing Zoruas and have a Zorua in slot 2, 4, and 6. If I could colour the background of the boxes I wouldn't have to tab out and keep track of what Zoruas I still need in another program, I could just set up the individual box backgrounds to be coloured based on IV and then arrange them as I need.
