Thanks for building and sharing this! As a feature request, which would likely be the decider for me using this, would you please consider an integration into koreader? As far as I know, koreader is the #1 open source app for ereaders. If anyone using their ereader can use this, you can expand your userbase outside of those who just read on mobile. I don't think I'm alone in never wanting to read an actual book with my phone. At any rate, best of luck and great work getting this shipped!
