If you can live without the "HUD entirely off" feature (CTRL-ALT-G instead), then it's an easy fix. Just change the CommandListToggleHud to have only the following:I might try to follow your advice with the default and using hunting, but it's not something I ever done before so might take a while before I get around to learning how to. Especially since I don't actually fly without HUD (I'm a combat pilot), but was testing as I was trying to figure out what does what and encountered that "bug". I'm sure I'll do it at some point!
Code:
[CommandListToggleHud]
$hideHUD = 1 - $hideHUD
This will toggle the canopy glass part of the HUD only (circles around planets, stuff like that).
