I'd *really* like to see an interface to server-size IMAP search that functions very much like GMail search -- don't require users to specify which fields they're searching, just let them enter a search term and search all fields in all messages (via the IMAP search functionality, letting the IMAP server do the work) and then return the results.

How soon could this be added?

With this, RoundCube + a good IMAP service like Tuffmail could really be a superior offering to GMail.

Check out http://www.rourkem.com/2006/10/20/why-i-dont-use-gmail/ for what I think GMail still has that RoundCub is missing.

Thanks,
Rourke
