thats certainly an idea, tho fade was but one example, to draw one/anything is a mouse move eye strain time user (hitpoints are small tbh anyone over 40 which will be me soon wants to avoid that!), to have 1 bar or 2bar fade or common shapes handy for pan or anything else ready to roll for all users is well within the realms of a sensible suggestion i thought.
i'm happy to create my own or nab someone elses, but that wasn't the point.
enough OT
