It would be great if it was possible to use Joplin in a smartphone car mode (Apple CarPlay and/or Android Auto).
The main use-case would be that while driving, someone can ask Siri or Google to open their Joplin app and then the driver says "Add note this is a test" and then a new note would be added to Joplin saying "this is a test".
The other major use-case would be to read notes, such as if the driver says "Read latest note" and then it uses Siri or Google to speak the note contents.
These car systems already have dictation speech recognition and TTS capability, but the app needs to be set up to support Apple CarPlay and/or Android Auto before it will work.
