Hello! Thank you very much for your support! I don't know how that plugin you attached works, but I can try to do it. Due to the file system used in NW.js and the browser's security restrictions, there are some impediments, which can complicate development (This already happened to me with the Itchio plugin) I can only guarantee that if I can get it to work, the system would work on Windows systems. Is that okay for you? I would need more information on how you want the plugin to work.If you want, you can contact me via email and give me a more detailed explanation there:
