How does this go beyond what you can do with mutt? Plus mutt handles IMAP out of the box.

It mimics the gmail look & feel, i.e. one line of text represents one thread in your inbox, and when you open it, you get all the messages of the thread (with read messages collapsed), instead of precisely one message.

Edit: also fast (!) full-text search thanks to Xapian, tags instead of folders

folder-hook . "exec collapse-all"

set sort=threads

set sort_aux=last-date-received

Yup. I do this since I'm used to za in Vim for toggling folds:

    # Collapse all threads by default, except if 
    # there's new mail in one.
    unset collapse_unread
    folder-hook . "exec collapse-all"
    # Toggle collapsed threads with za, like in vim.
    bind index za collapse-thread

Unfortunately this won't install on my mac. After playing with it for a while I'm giving up... because I simply don't have the time.

Too bad, I was really excited about this.

AFAIR, William Morgan also used Mac OS X, so I am surprised it doesn’t work for you.

Sooo... it's pine?

mutt cant display the first few words of an email in index view like sup does. i love gmail therefor.
