Why isn’t there a plugins page on the mineos webui? It could be as easy as uploading your plugins to the server from the webui and managing the plugins folder within the webui as well.
Creating a plugins page requires a lot of UI work, both to include the handling of file transfers, and file tree navigation. I can’t think of any way in which these features could be so simply accomplished–and also done so in such a user-error-reducing way that it solves more problems than it introduces.
When it comes to file transfers and tree navigation, SFTP clients do this in a way that is far too polished and rigorous for me to think a home-made one will compete.
