The text in folders with children is always bind to expand/collapse its children. In some cases one would only want the plus/minus-sign to expand/collapse the tree. It should be possible to set text and a link as folder text. At the moment, if I put an <a>-tag inside a folder text, a click on it expands/collapses the folder AND opens the link.

Commenting out line 66 disables expanding/collapsing when clicking on the folder text. Plus-sign still works.

		applyClasses: function(settings, toggler) {
			this.filter(":has(>ul):not(:has(>a))").find(">span").click(function(event) {
				//toggler.apply($(this).next());
			}).add( $("a", this) ).hoverClass();

Maybe one could implement a new option?
