Hi,

I've just released the first version of notmuch-labeler. This package
improves notmuch way of displaying labels through fonts, pictures, and
hyperlinks.

By default notmuch presents email labels as plain text. This package
improves notmuch by lettings users choose how to present each label
(e.g., with a special font, with a picture, ...). Additionally, this
package transforms each label into an hyperlink to show all emails
with this label.

See screenshota and more at https://github.com/DamienCassou/notmuch-labeler

If there is interest, I can help integrate into notmuch itself.
