[RCD] Example code for list_prefs_sections hook?

I'm trying to wrap my head around how the hook for list_prefs_sections works. I don't think my brain is up to the task today, so I was wondering if anyone has a small example to show?

I'm assuming: ... $this->add_hook('list_prefs_sections', array($this, 'opt_block')); ...

function opt_block($args) { $args['cols'] = 'optlabel'; $args['list']['optlabel'] = array( 'id' => 'optlabel', 'section' => 'Option Label'); return $args; }

Digging through the program/steps/settings/func.inc I can see that list is a copy of $SECTIONS and I have no idea what cols is used for.

Anyone have a quickie example? _______________________________________________ List info: http://lists.roundcube.net/dev/
