Smooth parameter adjustment in all fx

I noticed in the newer effects like Poly Flanger, the number of voices parameter can be adjusted by mouse dragging. Would be great if you could bring that to all the older effects too, like Taps in Cluster Delay and Voices in Flex Chorus (which currently have a popup menu). The new workflow is so much smoother.

Also: while the popup does make more sense for the Style/Mode parameters, it would be nice to at least have mouse scroll switching for those too. (Or maybe even: single click→menu, drag→instant mode switch, if that’s possible)
