[Feature Request] Add support for Glance Daily Agenda

[polygonwood]

Have a look at this application https://github.com/JayFiDev/Glance-DailyAgenda, it also has a companion app for iOS https://github.com/JayFiDev/Glance-Companion (though I'd be looking for a web or Android alternative implementation for that). The idea of a minimalistic representation of agenda / to do list fits the concept of Papyrix reader.
