Tested on Chrome on Android, Firefox won't work just yet. Enjoy or whatever.
Probably won't be hosted on WordPress.org (they require the shitty GPL license). Probably will be a NANY 2020 project.

1. Unzip the zip file into wp-content/plugins/
2. Activate the plugin.
3. Donate 1 Million USD to me because I need it.
Good luck, have fun, whatever.
