| Hi Brian 
Thanks for taking the time and documenting nodes.
 
I'm thinking of an alternative solution for documenting nodes. 
There is a new feature in NE Plus called "Tooltips ". You can Alt + Click on nodes  to see the node's tooltip. 
It uses the "desc" property to show a tooltip on the canvas. 
Like this: 
Multiplexer_Mux.desc = "Multiplexer (Mux) * To select input(s) by index number or a binary pattern"; 
(" * " characters add a new line to the tooltip.)
 
I left it untouched for most nodes except the ones I created recently. But, it's possible to write a simple description for them.
 
Or, We can use the translate function to insert new node descriptions on the fly. 
Check the Descriptions  section in the "NEPlus_Full_Dict.txt" file. ( It's a long file, search for: /* Descriptions */ )

I checked your "swRotary" node. It looks like a widget version of "Mux" node. :) I encountered a bug when cloning the node on middle inputs selected. 
Fixed the bug, added more input options 
Check this version: "Widget/SwRotaryTEST"
