Hi Tod
Merry Christmas to you as well!
Great idea - funny, I envisioned something similar when designing that HUD. I originally wanted multiple HUDs that could be placed for each curve, then realized the clutter that would cause, so kept it simple.
I think I'll model an attribute for curves - something to signify their prominence, with a switch that can be toggled on or off. That way, the setting can be made in individual profiles once, and remembered forever.
Thanks for the idea!
