Hi @Bernie . It is 16 days ago, when we talk about this app. BookLore is UI beautiful, but has some bugs like not discovering all books in folder.
See this post for more details:
Personally I recommend to wait for fix this unfortunate bugs and do not add this to Big Bear Repo at this time.
But You can test it, Your feedback would be nice. Developer has yaml file in docs. It can be easily runned.
