It seems to work Rated 3 out of 5 stars

The user interface is in the tools menu there where where it is written "theme test" if you click on this menu item a window pops up with a lot of options to click, like menus sidebars and a lot more, at the side of each option is a editor where you can enter your code, ... i think it works with css but from there i did stop my test because its not exactly what i search for... but clearly a user interface exists!

OK.... Rated 1 out of 5 stars

So... where is the interface etc?

Just installs and is nowhere to be found.

No visible way to use it. Rated 1 out of 5 stars

I installed it and have no idea what it does. It has no interface and no info on how to use it. So I can't really give it any stars.
