Widget persists todo items as a JSON, so in order to simplify JSON serialisation/deserialisation download a **json.lua** from this repository: https://github.com/rxi/json.lua under `~/.config/awesone` folder. And don't forget to star a repo :)
Widget uses your theme's colors. In case you want to have different colors, without changing your theme, please create an issue for it. I'll extract them as a widget parameters.
