[drewdrew21b]

Is your feature request related to a problem? Please describe.
Many people have self hosted libraries for books and comics. It would be great of this applicattion could utilize these self hosted services.

Describe the solution you'd like
If this application supportes OPDS standard, many of us could quickly see our libraries and read from our vitas.

Describe alternatives you've considered
If there are other supported ways that could accomplish this goal such as a different protocol or service, even if its proprietary I would be willing to set this up on my network (preferably a service that is available via docker).
