Hi @karthink , it is a great package to have!

Could we have an option to enable one caption per line? I find it much more readdable (for me) to use caption one by one instead of putting them together. Maybe something like elfeed-tube-one-caption-per-line, or elfeed-tube-caption-style with options:

I tweak it with `elfeed-tube-one-caption-per-line' as starting point:

(defcustom elfeed-tube-one-caption-per-line nil
  "If non-nil, show one caption per line."
  :group 'elfeed-tube
  :type 'boolean)

And change the quoted code with:

(string-join
 (mapcar (lambda (tx-cons)
           (propertize (cdr tx-cons)
                       'timestamp
                       (car tx-cons)
                       'mouse-face
                       'highlight
                       'help-echo
                       #'elfeed-tube--caption-echo
                       'keymap
                       elfeed-tube-captions-map))
         para)
 (if elfeed-tube-one-caption-per-line
     "\n"
   vspace))

(I believe this "\n" should be put together with `vspace', but this is only a rough demostration. :-))

Result:
