: A browser extension or bot that, when you click "Download" on the Flibusta site, automatically pushes the file to your reader's local storage over Wi-Fi.

: Since you mentioned (fb2) , the feature can be configured to automatically select and download the .fb2 version of a book by default, skipping intermediate "Choose Format" menus. Cloud-to-Reader Pipeline :
