There’s just one problem: it gets kind of claustrophobic when you are debugging a Sub-Tree, which could be transitioned out of at any moment, and when it gets transitioned out of you can’t know what is going on outside of it unless you exit to an upper graph, but now you gotta enter another into another Sub-Tree, but by the time you got here a bunch of things already happened… All of that gets even worse if those Sub-Trees have their own Sub-Trees and so on. Basically, what I’m trying to say is it’s hard to get a full picture of what’s going on with just one window. An option to “Open sub-graph in new window” would be an absolute lifesaver. It doesn’t even need to be a fully-featured window, just something I can dock and take a look at when I’m interested in what’s going on in Sub-Tree X or another window for Sub-Tree Y.
