As has been stated LittleNav Map is a really a useful tool but when I first used it I was i overwhelmed with it and parked it. So as another pilot has said just concentrate on learning the world map process until you are comfortable to move onto something new. I would be lost with LNM and have never used the world map for planning - its def something to aim for.
Happy for you to contact me directly if you need any help with anything!
Enjoy.
