But that doesn't help if you're planning a route without a connection to the internet.

Example: I plan a route at home, have an internet connection and all maps were downloaded automatically. Very nice.

But later on this day at a airport or somewhere without internet connenction I plan a new route and then I don't have any approach charts if they are out of date. Not nice!
If Skydemon had already downloaded ALL the outdated maps at home, there would be no problems later on.
Therefore, I am in favor of Skydemon either automatically downloading all outdated approach charts or starting the download via a central button.
As it is now, the situation is pretty unsatisfactory ...
