Hello,
I have seen the vid on the upcoming version of Navigraph charts. Very encouraging 
!
I would suggest the developers to add a feature allowing users to access, within the app, documents (ex OFPs, manuals, loadsheets etc, that a user can save, before or during the flight in a specific folder, or allowing synchronization with dropbox or google drive for iOS / Android apps).
I think this would be great!
Cheers,
Mircea
