First the BUG:
The issue i have found regarding the OPDS server while trying to use it in various apps:
The "Next" link becomes broken after a certain page (e.g. page 2) so any app trying to access the next page will fail with a 404.
Example for "Years" section, NEXT link for page 2:
Should be: "/opds/bookyear/2017/p/2"
Actually is: "/opds/bookyear/2017/p/0/p/2"
The same happens for "Series" and maybe other secitons.
Please add an option for the OPDS server to start automatically when Alfa Ebooks Manager starts.
Would be even better if the OPDS server would run standalone as a Windows service
