It would be great to have more badges available to display more info about components in both Perspective and in Vision. One idea that has been suggested by another user on the forum, is to add a 'Message Handler is used' badge to identify that a component is using a message handler.
One way to avoid cluttering of the badges area, is to also make the list of badges shown user-selectable so that we can show and hide those we feel are valuable at the time.
