Been saying this for so many years...:(

Absolutely, it's essential that Mailbutler incorporates two-way sync with Apple Contacts and Apple Notes. Jillian mentioned that there's already a two-way sync with Apple Reminders, which is great. Given that it's nearly 2024 and artificial intelligence is in use, users of Apple products have come to expect two-way synchronization as standard. Lacking this feature in Mailbutler, especially with Contacts and Notes, would be a significant oversight and could be a disadvantage for the service.

Or an app like busy contacts and busy cal. those are more superior for calendar en contact management.

This would be a great feature
