This looks very similar to calibre-web. Interesting to see if it's any better or just another option.
Irrelevant? It's fantastic. They won't give you DRM free e-books? Just take em'.
Removing drm from files is an issue unrelated to booklore. Audiobookshelf is the same-you use another app if you want to play your audible purchases where you want.
Drm hacking is a problem created by amazon, it should not be the central feature in a good media management app.
