Instructions unclear; my wife got mad when I told her she has to set an appointment for movie night.

This is awesome! I wonder how it will compare to the competition when it’s generally available.

Does anyone have any information about the other offerings mentioned in the blog post?

In the future, we intend for Appointment to be part of a wider suite of helpful products enhancing the core Thunderbird experience. Our ambition is to provide you with not only a first-rate email application but a hub of productivity tools to make your days more efficient and stress-free.
