Yes, I know it is a small "cosmetic" suggestion, but don't you think it improves readability?
- Make the figures on the speed and altitude strips to have the same background colour as the strip colour.
- Dont show the map image on the upper strips sections.
- Maybe make the strip figures font a bit smaller.
- Make a thin border on the actual speed and altitude windows.
See attached images. First one is the original, second one is what I propose you.
Thanks Petr.
