sticky magnifiers for easier node connection.

Sometimes it's difficult to connect nodes when zoomed out of the node editor, and even when you zoom in it's cumbersome to connect one node to another which is outside of the view.

It would be a good idea if there were two sticky magnifiers panels, one in the bottom left of the node editor, and one in the bottom right of the node editor. Then you could alt left click an area of the view to show that area zoomed in in the bottom left magnifier panel, and then alt right click another area of the node editor to show that area in the bottom right magnifier. Then you could easily connect two nodes by dragging between the two magnified areas.
