so, I've been quietly feeling bad about using Gmail all day (and Apple Mail before that, ahum). If I think about the single most critical feature that makes today's mail volume manageable for me (other than priority inbox), then it's conversation view: The ability to page through an entire mail thread quickly without having to go back to the index view, and without having to think about having to move to another message.
I think we have much of the infrastructure it would take to code up something for that in mutt. Main open challenges would be: - Display the entire thread in the pager; - figure out a way for the message actions in the pager to either apply to the whole thread, or to the message we think the user's currently focusing on; - figure out how to cut the right amount of quoting, but that could start with the current "skip quotes" code. Anybody up for giving it a stab? (Or did I maybe miss somebody already doing it? :)
