I often find myself searching the navigator for that element where I have an interaction tied to. It would be very helpful if elements that have interactions tied to it would have a small identifier. Or if in the interactions overview it would be possible to tell to which elements the interaction applies.
Another thing with interactions is that if I have selected a random element in the navigator, then go to the interactions overview to edit an certain interaction that interaction will be tied to that random element. In other words it's not possible to edit an interaction without also selecting it for the active element.
