Randomize roughen effect
When using the "roughen" tool, it's rare that I want it to be a consistent roughened edge. Assuming that many of us use this tool to introduce controlled chaos to a path, I think a "randomize" toggle (primarily for detail, as it appears size is already random) with parameters for widest gap and shortest gap between points would remove the process of roughening at a high density then painstakingly using the "smooth" tool to create variance.

Not a UI designer. But hopefully this clears up what I was mentioning.
Mitch, can you share a sketch that shows your vision of it?
