Two cool things relating to context

Restrict by Context

In your $plugin array add:

	'required context' => new ctools_context_required(t('Node'), 'node'),
						

Context keyword substitution

In your $plugin:

	'all contexts' => TRUE,
						

And in your render function use:

	$thing = ctools_context_keyword_substitute($conf['thing'], array(), $context);
