For the download part, I think it's better to get the user to the folder where he can find the file in two different versions. But I take it in consideration and I'll try to improve that part.

There is no obligation to use it, if you think it's easy, then good for you :) You wont need it.

It's just here to make you save some time, to help you taming some wild targeting selectors. If you can do it, without some helpers, then just don't use it.

Of course, you'll use this project ony if you have to deals with some more complex nth targeting on a regular basis.
