Node gouping and sub-graphs

[leissler]

In the dialog example, it seems that there is a grouping feature for nodes. However, when moving the group, it turns out that it's just an empty node around a couple of nodes and doesn't really group them.

So I think that a real grouping feature that treats all nodes in a group as one entity would be very useful since larger graphs quickly become hard to manage. In the best case, such a group should act like a sub-graph with its own inputs and outputs that can be re-used like a function.

Originally I had written it to behave similar to UE4 blueprints, where nodes are moved with the container comment as you suggested. But I was running into a good amount of undesirable edge cases that made me strip it from the 1.0 release. I've got #5 open already for this one.

For subgraphs, ideally I'd like to keep that as a separate feature where you can extract a group of nodes into a separate graph asset with explicit inputs and outputs - similar to UE4 macros. I know I started on an implementation but it never made it into the samples project. My graphs tend to be pretty lightweight so I haven't spent much time on quality of life features for large graphs.

I agree that comment-move and sub-graphs are two separate issues. So are you planning on integrating real subgraphs similar to UE4 macros?
