I agree, the new key overlay was first behind the darkness created by the Flashlight mod and it was later put on top of it so we could see it at all times. I think the same should be done with the scoreboard.
A request to make the ranking bar visible on the left when watching other people's replays when they used the flash light mod. YES!
It is very exciting to see people climb the ranking when watching a replay, but it is currently not visible when you watch replays or play in flashlight mode.
Tbh, this would partly ruin the meaning of FL. I do not play it much, but what I found cool about it was the fact you have no references at all while playing. With this feature you would give an advantage (even if just little) since you can better calculate things on the left side of the screen. [just personal opinion, obviously]
