Control visibility of lightning component using slds-hide

<!-- Component Markup -->
<div aura:id="yourIdentifier">
    <c:Your_Component />
</div>

/**
 * Controller Method
 */
showComponent : function (component, event, helper) {
  $A.util.removeClass(component.find("yourIdentifier"), "slds-hide");
},
hideComponent : function (component, event, helper) {
  $A.util.addClass(component.find("yourIdentifier"), "slds-hide");
}

This is great, didn't know about 'slds-hide'. I'd provide an improvement by using $A.util.toggleClass. Can simplify this to a single method like so:

toggleComponent : function (component, event, helper) {
	$A.util.toggleClass(component.find("yourIdentifier"), "slds-hide");
}
