This is a really great plugin, and I enjoy using it very much.
However, I now have a customer that wants to change the position of some of the links. For instance, he wants to have the register in the top right corner, and the forgotten password below the form.
As the li elements are not classfied, I have no way of catching the elements, without changing the code itself, breaking the updatablility of the plugin.
My suggestion is to give the different li class according to function. I can see in the code that they are coded directly, so giving them a standard reference should not conflict with anything.
