OK here we go! In about 12 hours or so I'll commit the breaking change. that means if you know any tags which you want to change the letters or parameters for speak up now so we dont need to do another break.
I am contemplating adding an optional param to the bars at the start to say what type of bar it is (because I want to allow slider type instead of fill type, and a mix of both) and the first param is more logical...
