So I have been watching alot of Zaphods vids and he is always checking his commander/engineer build queue and it brings up an overlay with the silhouetted buildings and lines showing movement paths, rally points with a line from factory to rally point, etc. If I hit shift all I get are the silhouetted buildings and the patrol and move points (which are hard to see) but no lines. How do I see all those lines? That's a really useful view.
You can also tap shift to see them if you don't want to see them all the time. You can also tap caps lock to toggle them on and off without going to the settings.
