Ability to change HUD opacity

[DementedCorn327]

For the taxi arrows opacity there is an existing thread including that request:

Taxi Arrows Need Complete Re-Work

I’m scooping all suggestions up and putting them here. Current taxi arrows; …are elevated too far off the tarmac thereby blocking view …show through the bottom of aircraft while using them …have no way of being assigned a simple key command …ugly as “H-E double toothpicks“ and a complete immersion killer They need to be redone. Having them show through the cockpit can actually disable cockpit point and click commands. They are so huge and blocks forward visibility to an extent while taxiing…
