Parameter smoothing/possible feature request

I'm curious about parameter value smoothing in RNBO. I currently have a rampsmooth~ after every param, as they are largely fed by MIDI, and even mouse interaction can be kind of janky with the parameters with large value spreads.

It's more of a security blanket though - I'm not sure when it really necessary to smooth a param output or not. I'd rather not find out on a case by case basis since I have 30+ parameters! If smoothing is usually needed on param output to avoid zippers, would it make sense to incorporate an @smooth <num sample up> <num samples down> attribute to param?
