Make it easier to understand if an event would not trigger in an experiment, for example by Implementing a debugger tool when editing a variation, showing if specific elements/events that are supposed to be tracked for the experiment, would not trigger. Or, implement an easy way to test (with an URL validator maybe) if a click event can be triggered from specific URLs (for example, if I want to implement a click event in a global page and I want to quickly test multiple URLs).
