  * The following attributes are used when constructing sections:
  * - "label": a user-visible string to use as section heading
  * - "display-hint": a string used to determine special formatting for the section.
- *     Possible values include "horizontal-buttons".
+ *     Possible values include "horizontal-buttons", "circular-buttons" and "inline-buttons". They all indicate that section should be
+ *     displayed as a horizontal row of buttons.
  * - "text-direction": a string used to determine the #GtkTextDirection to use
