Ability to check availability of meeting invites
When I receive a meeting invitation, I would like the ability to click on the invite and see my calendar on the time and date of the invite. This way I can see what else Ihave going on before I accept or reject the invite.
SparkMail has a nice way to do this.

Yes - this is also nicely integrated into gmail (right in the message window) when you receive an invitation.
