Just two little things to mention:
a) The language is hard coded into the extension. That's not state of the art.
b) It seems the module output cannot be overridden via template override. At least it didn't work for me (with Joomla 2.5) and I had to alter the module itself.
I installed a number of other category list creating extensions, to be used with another extension (Modules in Content) which would allow placing a module in the content of a page. None of the others worked when placed within the tags, but this one did! They both work beautifully together, allowing me to create a list from a category to place on the page content without having to create a lengthy submenu.
