Hi, I can set color per line using notmuch-search-line-faces. But I would like to specify color per line field, i.e a color for date, another for authors for exemple. To do this, I would like to use a 3-tuple list for notmuch-search-line-faces: :type '(alist :key-type (string) :field (string) :value-type (custom-face-edit)) The problem is function notmuch-search-color-line take a non structured line in args. Then it is needed to parse it to find out field. Do you think it would be possible to add a mecanism which permit to color a field during line building ? Thx, Dal
