Hi WN,
It was a pleasure to review your RevSwitch file, to see the numerous corrections to the SwSPDT.js file that I did in an attempt to modify Max's Switch node.
Number of inputs and outputs, for each of the 3 datatypes was done.
(Code from Logic > Split node, I see.)
I broke the bezier color somehow.
I see that you modified the bezier, somehow, using the "same" code.
You introduced the dataNull.

Even though the RevSwitch function is already covered in the Logic > Split node, the Bezier indicator curve is nice to see.
