Hello there!
The default Heading Bug is in a dark blue on a dark background, so not very easy to see, under a number of different light conditions.
So I suggest another submenu under "Screen Settings" called "Heading Bug Color Preference".
My own preference would be something like RAL 2005 Brilliant Orange, or RAL 3026 Lumious Bright Red, this is by no means aviation standard, but much more visible...
Kind regards
