Yes, I'd be more than happy to provide a SASS version, I'll look into that, hopefully this evening as it shouldn't be too long to make one at all.
Do you feel the documentation gets across what can be done with it clear enough?
For instance, This doesn't need a js dependency but you could easily mock progress using a keyframe animation on a particular progre(c)ss etc. I am going to try and make some clearer docs and try add some feature attributes, or classes.
I just want it to be clear to people that you can add it to existing elements I think without changing design.
Thanks again for the feedback and I'll get a SASS file in as soon as I can.
