LOL. Yeah, that is a bit of a mystery at first. I would like the graphics to be updated on the empty components. This is how they work:

Category or Family into the back of it. Just act like there is actually a input circle on the left.

I hope we get this updated at some point.

the BuiltInParameter Picker still eludes me.

Me too.
