Living in the Karibean and using the Mavic regualry there is two things that is extremely annoying. First the theme that the user interface is using. In strong sunlight it is impossible to see text or any grafic due to the color combinations together with the font used. I really would apreciate a possibility to chage that to a high contrast theme.
This makes it really annoying when you are on islands and get the constant no fly zone warning and have to unlock the zone you are in. Since it is impossible to see the check box and any of the words I sometimes have to abort the flight session if I cant find a good shade anywhere.
Yes, there are many other solutions to this but a high contrast theme would be extremely helpful.

Hi, there. Hope that you are doing great today!
