One thought that came to mind while I was using Littlenavmap is I would love to make multiple tabs of the map with my own view settings. As it is now, you can show and hide just about everything which is great. I would love to have, for example, a second tab that I have set up to show airways+VORS+xyz without terrain+ILS plates+abc and switch between the two (or more) views.
Just a thought if the dev likes the idea and is looking to add more features.
