The automatic chart overlay feature is good when it works, but it seems to not work I'm situations when more than one chart is available.

It's kind of frustrating that this is the case, because it's usually exceedingly obvious which one to display. I can think of some heuristics that could be used. But also, if that's deemed impractical or inelegant or whatever by the developers, then how about giving users some control if this? I should be able to state when planning a route which chart I would like overlayed depending on my position in the nav plan.

I recently found out about the georef'd maps, this is a very powerful feature. However, to use them you need to search through menus to find them, just at the moment the workload is high. Also more complex airports have more items, making it more difficult to find what you need, exactly while you need them most. I read above you were not happy with the feature to automatically show them. Why not display extra buttons at the right side when we are (almost) in the area of such a map?
