Download audiobook to device

[PinkMusen]

Sometimes you may be away from wifi or have limited data, it would be nice to be able to download an audiobook (or more) to the device so that it can play from local storage instead of streaming it like the audible app does.
Is this something that's planned for the future ?

This is already supported for both android and iOS

@advplyr I think this might be a regression in the latest iOS app? I filed a ticket with details here:
