Hello!

I'm looking for some additional options for organizing my emails.
Splitting rules give me a very coarse-grained organization of my
correspondences, but I'd like to have more flexibility.  Call me a
hopeless follower of trends, but the solution I have in mind is to add
tags to my email.  This has been done successfully for Apple Mail [1]
and for Thunderbird [2].

One solution seems to be adding headers to mails (either X-tags or
X-keywords).  I've tried to do this by just hitting 'e' in the summary
buffer, but get a message that the backend (nnimap) doesn't support
editing.  Is there a way to insert new headers into a mail from within
gnus (specifically, one that works for nnimap)?

I'd also like to be able to limit and search by these headers.  I hope
that eventually mairix will add the ability to index arbitrary headers
[3], but another approach might be to also store the tags using IMAP's
Keywords.  Is there a way to use gnus to add IMAP keywords to a message?

Thanks for any help!
