Persistent Graph Node Preview
When you hold Ctrl and hover over a graph node, you are shown a little preview window of the corresponding page. It would be beautiful if that window could be made persistent.
How this could work:
When you activate the node preview window option (maybe from the graph settings), a floating, resizable, and minimizable window appears on the graph. The window is initially empty (or displays a set page), but whenever you hover over (or select) a node, the node’s corresponding page is displayed in the preview window.
