I Should be able to from a calendar entry, click on the number to call the customer/ attendee, not navigate away from the calendar card. Also, why cant I click on the address to open maps from a contact card under the contacts tab?

Once the appointment is done. I find myself having to go through multiple part within the app to communicate with them. Or to go to their house as a follow up when the job is getting done for example.

Why use multiple parts of one app, when maybe it should all be in one location.
