I would like an option to reverse the way a fixture with cels automark.
I personally would like the cels default at zero and the masters channel default at full. There are fixtures where the master sets the color temperature and the cels do RGBW colour. Setting it up as described before avoids strange fades when you crossfade to another state. The disadvantage is that cels do not mark, because the fixture is never below 0%.
The feature request is: make an option to treat cels as normal channels with attributes for marking.
