arent mark cues quite important when programming catalyst?
Many programmers (myself included) choose to write their own mark cues. This allows me to control what is marking, when it's marking, and the time it's marking in. It also allows me to use a consistent numbering scheme so that all of my mark cues are easily identifyable in the cuelist window.
Personally, I always make Intensity Palette 1 a palette with every fixture in my show at 0% intensity and I call this palette MARK.
