My suggestion for the sequence tab would be something like 1 rotation, or a way to stop the animation. Even if it's a stop after x amount of seconds.
For example, I want Merry Christmas to scroll 1 time, then stop. If I add it in at the beginning of the song it will scroll the entire length of the song, unless I figure out it takes 10 seconds and then start another effect then to stop the scrolling.
So either a duration of the animation or a stop after x amount of seconds would be great. I'm mostly doing text scrolling at this point, just a suggestion--thanks again Matt!
