I have a few suggestions for some AddOns.
- This is probably more appropriate for Lightning. An AddOn that implements the Seven Habits of Highly Effective People weekly planning using roles, goals, sharpen-the-saw, and mission statement. This AddOn could open up new possibilities for Thunderbird. One way that it could help, it could attract business adoption of TB. The second way it could help users to make use of this special way of planning and leading. Please consider this.
- AddOn to create groups for emailing.
- AddOn to make a “ConstantContacts”-like email.
