Updated! 
Some errors fixed, like file names no longer duplicate. Also, you're able to toggle terrain-track conflict generation and display. I tried changing the yellow box to something more transparent so the actual terrain element could be seen in spite of the warning, but it was very difficult to notice that the warning was there. By toggling warning display off and back on, now, you can easily check what's underneath the yellow box, though.
