Configuring the Org-roam buffer display

Org-roam does not control how the pop-up buffer is displayed: this is left to the user. The author’s recommended configuration is as follows:

(add-to-list 'display-buffer-alist
             '("\\*org-roam\\*"
               (display-buffer-in-direction)
               (direction . right)
               (window-width . 0.33)
               (window-height . fit-window-to-buffer)))

Crucially, the window is a regular window (not a side-window), and this allows for predictable navigation:

• RET navigates to thing-at-point in the current window, replacing the Org-roam buffer.
• C-u RET navigates to thing-at-point in the other window.

For users that prefer using a side-window for the org-roam buffer, the following example configuration should provide a good starting point:

(add-to-list 'display-buffer-alist
             '("\\*org-roam\\*"
               (display-buffer-in-side-window)
               (side . right)
               (slot . 0)
               (window-width . 0.33)
               (window-parameters . ((no-other-window . t)
                                     (no-delete-other-windows . t)))))
