this overlay shows drivers in the order they have entered pit road and, if you are on pit road yourself, whether their pit stall is near yours (according to qualifying / provided you're not in a heat racing event). The display duration is adjustable and pit road times can be logged as well.
The overlay requires iRacing to run in (borderless) windowed mode.
