It would be cool to have a 'phase' parameter in the effects control tab, alongside existing Rate, Size and Grouping, similar to the way Avolites Titan has.
In Avolites they allow a 'degree' to be set for the Phase, which puts each light in the effect to be out by that degree. It is quite hard to explain in words, but it changes how often the effect repeats within a group of fixtures.
