In LiveWhale 2.x and before, the “categories” widget variable shows a text-only list of event types.

Since LiveWhale 2.21, you can set these to be links (which lead to other calendar results for the same event type) using the following config option:

$_LW->CONFIG['USE_CATEGORY_LINKS_IN_EVENTS_WIDGETS']=true; // link to each category result when using {categories} in widget formatting

This will become default behavior in LiveWhale 3.0.
