Customize colours quickly with 5 colour pickers on one control layer for the whole set. Easilly change the timing of the letter's transition from a slider bar from .04 seconds (1 frame) up to .52 seconds with each layer coming on one ofter the other. And if 5 is too many layers, take it down to even just 1 with the slider control.
*this is not a "font" that you type. It is animated elements on separate and distinct layers*
