It would be useful if, when zoomed in, there was an option to move the ‘camera’ with the plane rather than seeing the plane moving. The view could still be rotated and moved, but snapped to the plane.
A free floating camera would be great, I would also LOVE to gee the connections around my cubes in the other cubes to see if my branches match up.
If you right click, you can pan the 3D view. Is that what you are asking for?
