We all get emails that look something like this:

Let's have a meeting at 2:15, Monday, August 15th.  Beverages will be provided.

I'd love to be able to add an appointment through the email.  This is how
it would work:

1. Select the date information (or it could be automatically underlined or
whatnot)
2. Right click it
3. Click "Add Appointment"

The date will be parsed and a new appointment window will come up with the
date and time already preset.
