Ability to collapse graph frames
Complex graph can contain dozens of nodes and can get quickly messy and overwhelming.
Adding a frame around nodes is handy, but I would also like to be able to collapse /reduce the frame to get a clearer graph.

If you wanted to collapse a part of your graph, I recommend 'Create node from Selection' to you.
SD already sort-of has this feature if you consider how you can nest graphs within other graphs. My issue is with how it takes many steps to create a separate graph (setting up the correct input and output nodes so you can hook it up within another graph). I feel like there ought to be an easier way of creating temporary sub-graphs with any selected nodes, or as in your example, within a frame. Then SD can collapse them into this sub-graph that can be opened in a new tab for editing, since otherwise you'd need to leave a lot of space around it in case you wanted to expand it again.
