Tree view
Elfeed includes a tree view, which gives an overview over all feeds and tags. Invoke ‘M-x elfeed-tree’ to open it. The feeds are visualized as a tree using the feed auto tags. The first auto tag is the root node, the second tag comes below, and so on. Feeds with the same auto tags are grouped together. Since ‘outline-minor-mode’ is enabled in the buffer you can use ‘TAB’ and ‘S-TAB’ to fold like in Org-mode buffers. Use ‘RET’ or click on tags or feeds to show the corresponding ‘elfeed-search’ buffer.
For example the configuration
emacs-lisp
(setq elfeed-feeds
'(("https://yhetil.org/emacs-devel/new.atom" emacs lists devel)
("https://yhetil.org/emacs-bugs/new.atom" emacs lists bugs)
("https://sachachua.com/blog/category/emacs-news/feed/" emacs news)))leads to a tree of the following form.
