This is almost exactly what I was looking for. It logs Google Analytics events, and is actually a lot nicer than the Chrome extension for that (Event Tracking Tracker) in some ways, because it notes page loads, which makes it easier to distinguish events, and loads a separate tracker for each tab, which allows you to track on multiple tabs at once more easily. Also just prettier.
One drawback: It lists the "Category", "Action," and "Value" for each event, *but not the "Label"*. I don't even have values on my events, and often distinguish them by labels; adding "Label" values, or the ability to add or toggle them, would be a big improvement.
Thanks for making this!

Doesn't work. It just doesn't log a single event. Not much more I can say about it.
