Aha. Yeah, I got a "shuffle" button in 4 as well. Put this in the list of "undocumented and/or inconsistent features," tho. I assumed it "shuffled" the user-entered values -- like most other uses of a "shuffle" button do. But now you got me thinking. Given the "random object" function in the particle generator, and throw in a few splines, and you could SO make a Jack Kirby-style "Doctor Strange" scene....
