Question 4.13

I don’t like the layout of summary and article buffer, how to change it? Perhaps even a three pane display?

Answer

You can control the windows configuration by calling the function gnus-add-configuration. The syntax is a bit complicated but explained very well in the manual node "Window Layout". Some popular examples:

Instead 25% summary 75% article buffer 35% summary and 65% article (the 1.0 for article means "take the remaining space"):

(gnus-add-configuration
 '(article (vertical 1.0 (summary .35 point) (article 1.0))))

A three pane layout, Group buffer on the left, summary buffer top-right, article buffer bottom-right:

(gnus-add-configuration
 '(article
   (horizontal 1.0
               (vertical 25
                         (group 1.0))
               (vertical 1.0
                         (summary 0.25 point)
                         (article 1.0)))))
(gnus-add-configuration
 '(summary
   (horizontal 1.0
               (vertical 25
                         (group 1.0))
               (vertical 1.0
                         (summary 1.0 point)))))
