Adding events from emails is nice, but I'd love to be able to add an event from taking a picture of a poster or a flyer. I see ads for concerts, rallies, art exhibits, and so on whenever I'm walking around town or visiting the local library. I'd love to just snap a picture and have the details uploaded to my calendar.
But this requires every poster creator to add an ugly QR code. Plus, QR codes just take you to a website and then you have to add info to your calendar manually. Bonus points if they support .ics but that's rare.
