LYH DOI Tools

● A Chrome extension to add Sci-HUB or Lib-Gen download icons to every DOI-link on the page, with various other small changes to make scientific paper downloading less annoying.

● For user guide, source code, etc. : https://github.com/liyuanhe211 /LYH_DOI_Tools

● Features:
    ● Add a download button to every DOI on the page.
    ● Directly download PDF from citation info with the context menu option or use the shortcut [Ctrl+Shift+S].
    ● Batch download PDFs from Lib-Gen for all DOI found in one page.
    ● Jump unnecessary clicks to make browsing experience smoother:
        ⚬ [Sci-Hub]: Click the "Open" button for you.
        ⚬ [Lib-Gen]: Click the "GET" button for you.
        ⚬ [Lib-Gen]: Auto refresh when 503 is triggered due to download several files at once (very useful for download large batch of files).
        ⚬ [Wiley]: Skip the Wiley ePDF page and direct download a PDF.
        ⚬ [x-mol.com]: The totally meaningless waiting period (a few seconds) before redirection when searching references on x-mol.com.
        ⚬ [Scifinder]: The need to click the single DOI link when opening Other sources on SciFinder.

● Explanation of required permissions:
        ⚬ "tabs" permission: The extension needs to know the content and URL of the tabs to find DOIs, and to modify the content of the webpage to add download icons according to the found DOIs.
        ⚬ "storage" permission: To store settings like preferred sci-hub domain and other options.
        ⚬ "contextMenus" permission: Add a contextMenu item as a quick way to access x-mol.com search engine.
