One thing I miss with using RGB is the ability to have multiple colors on at the same time. My fix for that was to turn every other bulb an alternate color, i.e., red, green, red, green and on and on. I have done that for my windows and it works, but it was a pain to program. So an option to mix bulb colors would be nice two colors would work, three different colors would be even better. ie. red and green, green and blue. red, white and blue. Just something more to add to your list.
