Just in light of recent posts about how to move groups of nodes.
Given you can SHIFT click on a node and all attached nodes are also selected allowing moving of a group of nodes easy, I see a slight problem:
Now and then you use the comment node to write comments.
They aren't selected when you do what I just said.
Allowing them to have an input (best option of the two I think) when you SHIFT CLICK on a group of nodes, the comment nodes are taken along also.
Yes, ok:
You could GROUP the nodes.
That has a problem if you are dynamically editing that group of nodes, adding new nodes isn't as easy.
You have to deselect the group and then regroup them.
Just a thought.
