Suite à l'atelier, voici le code qui permet de trier par ordre alphabétique les blogs
(defun my/elfeed-sort-by-source (a b)
"Sort Elfeed entries by their feed source."
(let ((feed-a (elfeed-feed-title (elfeed-entry-feed a)))
(feed-b (elfeed-feed-title (elfeed-entry-feed b))))
(string< feed-a feed-b)))
(setq elfeed-search-sort-function #'my/elfeed-sort-by-source)
