I’ll agree here - I made sure to have the mirror set up exactly how I wanted it, CSS, config, modules (minus one I couldn’t find) etc, long before I attempted to program my first module. . I then dove into the module building using the previously mentioned jsfiddle.net to create that missing module for me.
Due to work obligations, I haven’t been able to get back to it, but I plan to do that soon, and fix up things that people have asked for.
