It'd be super useful for me at least if you could add your own events to the calendar, e.g add a harvest date for something so you don't forget. You would only be able to do this with your own calendar though not the one at pierre's. Let me know what you think of the idea! I think it would be a useful way to keep track of things without having to have a notepad open on your computer or have one in real life to write everything down.
