Debugging tool for Dynamic Tag Manager

There exists options to debug the tags fired from Dynamic Tag Manager but these options require the user to be tech savy.

It would be much easier with a graphical tool that let people see all the information about which tags did fire and which tags did not.

Furthermore such a tool could, for example, help a user to click on a site element and retrieve the CSS selector for the selected element. That way the process of creating data elements would be simplified.
