Nah, nothing cool or interesting unfortunately, it's things like extrusion widths (AFAIK there's just an extrusion multiplier in Prusa)

I mainly use it to get badass supports and rafts that leave the bottom of the print looking good. The trick is, on the top layers of the support material, have the lines less than a mm apart, then under extrude it dramatically, this leaves a really brittle but quite solid layer that doesn't tend to stick to the print very well but gives good support.

I'll see if I can find the screenshot I took of all my support settings if you're interested.

I almost forgot.

Prusa hides some of these settings..

This gives some kickass supports. The settings for the z distance needs to be adjusted according to your layer height. Also, this is an old screenshot, I now use tree supports, but all the support interface settings is what actually counts.
