My suggestion is to add a 'start size' and an 'end size' slider/option in the trail config menu for platinum users. Currently there is a "Width" option, I assume this just sets the start size and the end size is 0. I think having it just clamped at 10 and 0(like width currently is) shouldn't cause any issues. A benefit of this is allowing users to have different sized trails, ones that start small and get bigger, to create many different effects.
