While I agree that a real settings menu could be an improvement, they have made the settings experience better. They show a searchable annotated list of all the default settings on the left, and when you type a setting key in on the right it will show suggestions for possible values.

Looking at it just now, I also see that they added categories, and little edit buttons when you hover over a setting which allow you to click on what option you want. It's a bit strange to me that they're slowly turning a config file into a settings interface, but I guess it works fine for a Developer-focused product.
