Yes a toggle feature would be preferable. Thanks!
You can have your own half-assed version of this feature by making a clone folder of your skin and removing the combo colours from the skin.cfg. Then you can choose between the two, just like a toggle.I had already tried that when I was figuring out how to make my own custom skin. Its just that sometimes I think the beatmappers choice of combo colors really helps improve the feel of the map. I do not want to use the skins that come with the maps as it it to hard to play when always changing skins.
TBH I would prefer a whole bunch of toggles, not just combo colours. Toggle for invisible followpoints, circle transparency, invisible HP bar, etc.
