Marco, 
>> Could you please provide that N.E. package also for the V3? <<
 
I've always believed that NE was the same for both v3 & v4, 
but if it doesn't work for you with v3, then perhaps not.
 
I have not used v3 for at least a couple of years, 
& sorry, do not have a v3 version of NE to upload.
 
Pilou,
 
.>> Have you a web site different than Instagram because access is limited when visitor has no Instagram account! <<
 
Yes, I have a website:  www.jameshargraves.com ,however doesn't show any examples of nodeEditor experimentation. As far as limitation on Instagram, IFAIK you don't need to be registered to view post. I only started using it because the swiping of multiple images seemed like a good way of showing node circuitry, which tend to extend horizontally.
 
Alex,
 
.>> Circle Packing <<
 
Yes I will add this as a node proposal. I first need to contemplate how it might best be implemented.
 
Thanks 
James
