What app do you use to manage your library and read books?

I am currently using the default library of the Boox device, and reading with NeoReader.
However, it seems that it cannot be managed well with the default library (or maybe I have not found the item to customize):
- When searching, the book will search the entire library instead of the sub-library as I expected.
- Cannot search by an author's name, or by metadata content.
- Cannot mark a book as favorite, and can find it at any time in the Favorites section.
The things I expected, Moon+ reader pro can meet well. But it is quite laggy when used on an e-reader.
Do you have any other suggestions?
I'm new, so sometimes I'll have silly questions.
Thanks for reading.
