Sort of. It would be more useful to be able to see the whole path somewhere.
Also, although "truncate start" and "truncate middle" do what they're supposed in the result pane, unlike "truncate end" and "do not truncate", the hover over doesn't display anything.
As a compromise, is there any chance the hover over could be changed to show the whole path, possibly as multiple lines, regardless of which truncate option is used? The current hover over is limited by the screen width.
