I saw many screenshots of the colors before getting X3, but it wasn't until I actually used them on my own screen did I see that they
1. Looked less ugly
2. Saw how much they will help AT A GLANCE discern what "section" tracks are in
I've always used folders to keep everything separated and have used track icons for as long as they have been available, but this really adds another level to the quick eying of a set of tracks to identify them. Can't wait to get more into the use of X3 to find more gems like this that make a bigger difference than you thought they would.
