Is there a way to toggle these red lines? As in: I could press "F10" and the red lines come on, press it again and they disappear? Or alternatively, when I hold down F10 I can see the red lines, and when I let go of the key, they disappear? Better if they fade in and out smoothly, over time, even if it's just half a second.
I wouldn't need to see these red lines all day long. I would probably only need to see them once or twice during the match.
If I had to choose between never getting red lines, or they are always in my face whenever I zoom out, I would prefer never seeing them.
And if they were toggleable, we could see them even when we are zoomed in more. You wouldn't have to zoom out just to check if a passage was walkable.
