Hi Tim,
How about ‌a feature that allows to download all updates regardless of kind, with just the press of one button?

Another alternative might be to automatically check for plates along the planned flight coridoor and download them as well as any specified alternates. Coridoor width could either be user-defined, a product of the aircraft speed (since faster aircraft have more range options for diversions), a product of the route length, or a product of the number of available airfields along the route (e.g. If you're somewhere remote, the nearest possible diversions may be beyond the range of the selected coridoor). Personally, a default of 100nm (50 each side of the planned route) would be good for the speed and range I tend to fly - i.e. about 20-30mins of flight.

This would also avoid having to download an entire AIP for a country just to be sure you capture all possible diversions, therefore saving both bandwidth and device storage.
