Compose in a tab

This extension is a Mozilla Messaging experiment whose broad goal is to update the whole composition process. This includes:

  • rewriting (most parts of) nsMsgCompose.cpp in JS,
  • integrating an external composition UI (e.g. CKEditor),
  • add bonus features, like compose in a tab.

This is a proof-of-concept, so we do not expect you to use this for real. See the companion blog post for more details. Feedback and updates are welcome on Google Groups.
