I have noticed that there are some things I need to be able to do with groups, but can't. I've created a flow to demonstrate the issues I've noticed, which are partly to do with nested groups and partly to do with adding multiple nodes to a group.
I can add a new node (straight from the palette) to an inner or outer group. I can move an ungrouped existing node to an inner or outer group. I can't, however, move a node from one group to another without ungrouping it first; this (I suppose) makes sense when moving from one group to an entirely separate group, but I also can't move a node from a group to another group inside the existing one. (See the flow if this isn't clear!)
Also, I've noticed that I can't add multiple nodes or groups of nodes to an existing group, which means ungrouping one group and moving nodes individually to the other group, or else ungrouping both groups and creating a new group from all the nodes.
Here's my flow...

EDIT: I realised I didn't actually ask a question, but hopefully my meaning was clear... I suppose I'm asking (a) is what I want to do possible, perhaps by holding down a key whilst dragging?, or (b) if not, is this functionality slated to make it into a future release?
