Feature: contact link in appointments

Apr 11, 2012
Many times we add an appointment in calendar where we put a name of a person. A feature I thought is adding a link to contacts in appointments where you say their name.
As example, if I set 'Call Mark' a link to Mark should be added: while creating the appointment, like in Facebook tags, and a link to call him while reminder pops up.
Also, in calendar widgets phone number can be shown and so on.

What do you think?
