Hello! It would be good to have the possibility to import and export aircraft profiles directly from the app, without having to copy files to or from the Aircraft folder in the file system. The latter method is unelegant and feels like hacking the system. But most important, on some newer Android phones the folder is not accessable any more to the user.

It isn't a workaround, that's the way it works. Using the file explorer on mobile devices isn't something that most people are familiar with, so sharing via email, or sometimes even WhatsApp and similar, is how it's done.
