I run ABS on my laptop, and the main issue I run into is that when my laptop changes networks (i.e my vs my parents wifi), it completely breaks syncing. I wish you could set up a server and say 'this will be available on x,y, or z ip, try them all'

The android app does allow you to download audio books for offline listening, which I use a lot when driving. Unfortunately the 'playlist' doesn't seem to just autoplay the next book. I don't like interacting with my phone behind the wheel. Not sure if it has an android auto app or not.
