seriously easy and effective.
leave the default color yellow so people wont QQ
this way they could more easily be used as simple marks and indicators, for breakdowns, slow/fast parts, transitions or whatever you need/want to remember^.
(or add new type of marks with Text or whatever, that do nothing but mark^ and give visual feedback at a certain point of the track, however it would be easy, less confusing and ok with just colored warp markers imho^)
and since you need to prepare/warp/chop a song anyways to dj with Live,
you might aswell spent 1 sec more and place a red marker 8bars before the Break of a song, to be sure that you trigger the 8 bar dummy clip build accordingly!
