When I'm editing a template I often create a dummy template first and test the widget settings in that dummy template before pulling them into the primary template. During this process I'll have several templates open in several browser tabs and have mistakenly copied and pasted settings in the wrong direction. Why? Because I'm an idiot, but also because you can't see the name of the template you're editing while you're editing it.
Solution: When you name a template, have it's name appear on the blue folder wrapper, in the same manner as edited widget names appear on their folder wrappers. See mockup below:
