Display Viewer Node Output in View panel

Currently with a small screen, I always maximize the node editor area. However I need to toggle it constantly to see the output of the viewer node. The annoying thing it that while in maximized mode, it doesn't update the spreadsheet. So I need to double click the viewer's eye to update it every time.

Since it is a single column and the view menu has empty space, what about putting it there ? (duplicating it of course)
