It would be advantageous to have Actions on Components. At the very least an OnSelect action. At the best, the ability to create custom actions in your component.
A common example is the "menu" component - the ability to raise an Action when a menu item is selected to be acted upon in the App would be helpful.
Current workaround - use a Toggle and create formulas based on conditions around the component. Although this adds more dependency in the hosting app - which is what the component was intended to remove.
The behavior property which triggers when resetting the component has been worked on. And more custom ways to add behavior property has also been planned.
