So, I suggested this a while back but I have some new things to add to it. I also have a video down below of what it would look like(sort of).

Basically the idea is to have trails come like gradients, primary and secondary, so people can combine them. Now before you say that you can just buy custom trails, think about this, making gradients on a texture and being able to do it correctly is pretty hard, so this can be much easier, and you don't even have to do them both, primary would be a regular trail, and secondary would be just flipped.

Isn't that a texture glitch that happens when you click off your TB client and then click back on it?

I think that would be great, actually. Would be good if you are going for a simple look.

Yes it is a glitch, but I haven't seen it in a long time
