Horde/IMP has few features which could be thought of for Gossamer Mail 3.X

(1) Show/Hide Quoted Text (if there) while Viewing a message
(2) View Threaded doesn't apparently need the root and thread to be in same folder.
(3) A Brief Action Summary On Messages (ex repleid on ...., Fwded on .... etc) while Viewing a Message.
(4) Copy Message Feature.
(5) A full fledged Organizer.

Thanks
