The ability to take a picture of something or video for a calendar event you create, thus this picture syncs with the calender.
I wish for the picture or video or document one uploaded to be in the calendar event. so you can just tap on the calendar event to look at the picture, video or document. often I do this with Google calendar but I like the features in Microsoft Outlook. I think this would be a great addition for the app. or maybe I have just not discovered it yet.
