Viewports to help jump to important parts of the node graph

Proposal: Add a new feature to improve usability by allowing users to switch between multiple viewports of the graph (similar to virtual desktops). The number of viewports can be fixed (e.g., 2, 4, or 8) and can be cycled through by pressing a hotkey (e.g., v). Each viewport can be used to configure a specific part of the graph, such as the prompts, the results, or a zoomed-in view of a particular area. The position of the graph in each viewport should be saved so that the user can return to it later.

This feature would allow users to view different parts of the graph without having to pan and zoom around. It would also be more usable than trying to compactify all the nodes on the screen.
