Brainstorm

Technical Goals

• Universal Mail Cache (structure to be determined later) called LetterBox
• A usable automation interface, complete enough to not throw roadblocks.
• A well-designed plugin API that allows for additions and modifications to the application and triggered actions.
• A documented data storage format, for applications and workflows that need access to the email but not the app’s GUI.

UI Goals
To become the distinct, powerful email client it wants to be, Letters.app does not only need to be technically powerful, but needs to have an equally powerful UI.

• Gmail-like Mail Threading
• Proper Mailing list handling
• Proper in-line replying to messages
• format=flowed quotes system
