First one observation. The documentation states
“If you want to jump to a certain item in the graph, double-click it. It will open in the current window with a new graph of its relationships. To return to the previous document, choose Go > Back or press ⌘[.”
I think it is missing that you have to click on the main window to use the Menu - Go - Back option or ⌘[. You can’t do it while the mouse is still in the graph window - if you jumped from a previous graph window. The Menu is greyed out and the ⌘[ won’t work. The sign “<” above the main window works right away.
Would be great if ⌘[ would work from the graph window without activating the main window.
One more question, could the “Show Connections” option get a toggle to remove the nodes which have the connection type disabled.
