I agree that it shouldn't be automatic. I was thinking something like:

1. Select a bunch of blocks
2. Choose "create group"
3. A new "group" symbol appears (visually like three rectangles in a
stack, viewed from above)
4. The previously selected blocks are moved "into" the group
5. If you double-click the group, a box is displayed over the current
graph that lets you see its contents.

For the open group, I'm imagining something like a toolbox-style box
that can be dragged around the graph (and left open), complete with a
little grey title bar and a minimize button that restores it to its
"icon" state. That way you can leave it open and work with it until
you're done, then minimize it to its icon form when you've finished
working with its contents.

I can only imagine this making sense for blocks that don't need any
I/O - or even perhaps for blocks that only have connections among each
other. Visually showing connections going into or out of a group might
be tricky.
