Integrate with users' calendars (through Google Maps or device APIs) to enable these use-cases:

• Notifications for travel time to next calendar appointment location
• Using work calendar rather than a fixed schedule + work address

This feature should be reserved for paying users.

Introduce user preference for setting how many minutes in advance a "Go to work" or "Go home" notification is triggered. Currently this is hardcoded to 10 minutes in advance.

When Google Maps doesn't have traffic information for a route, duration_in_traffic is absent from the directions JSON response. This can cause a KeyError while creating a pin. Subsequent retries will keep failing and the task will eventually be retried indefinitely at the lowest rate of once an hour.

Timeline pins sometimes become outdated before they're relevant. Consider refreshing them with new info from Google Maps every once in a while. This should only be implemented for paying users.

Introduce user preference for Google Maps estimation optimism:

• Optimistic
• Best guess (default)
• Pessimistic

Currently, the system assumes a Monday to Friday work week where you start and stop working at the same time each day. Implement a more flexible way to set up Commute, including but not limited to:

• Enable/disable weekdays separately
• Allow setting up custom times for each day
• Disable morning/evening notifications separately
• Think of edge cases like people who go home for lunch

This feature should be reserved for paying users.

When going home, the current options should be offered:

• Go home at xx:xx (current implementation)
• Arrive at home by xx:xx

Users should be able to switch between these 2 modes.

Based on the home and work addresses you entered, display a preview map with markers + route in the configuration screen to help users verify their own setup.
