A Few Plugins

I love Scut and I think it will be useful in all my projects. I have created a few simple plugins that I think are useful and I was wondering what you think of including them in your project. I created a few more shapes, based on the code at  http://www.css3shapes.com/. I also created a mixin to remove default styling from a link. I find myself using this often for navigation and headers. I also created a list image plugin because by default browsers do not position the image well. This seems to be the most commonly used work-around. I am not sure how to add documentation so I was hoping you would be able to help with that. Here is a codepen of the plugins: http://codepen.io/gabrieldamon42/pen/oqEjK
