Clarify "Don't Send Response" option
When accepting a meeting, often I would prefer to accept without sending an email to the organizer. My previous boss specifically requested that we not notify him for every invite response. However, if you pick "Don't Send Response," that actually means "Hide my response from the organizer" and they are unable to see if you plan to come or not, if they went to check later. These should be two distinct responses: "Accept without notification" and "Hide my response from the organizer" so it is clearer what action you are actually taking when you select "Don't Send Response", and gives an option to "silently" accept without hiding it from the organizer.
