Yeah, I don't really see why this would've taken so much work as to justify charging for it? It's pretty easy to do manually, once you know the right tools.
You shouldn't think of this tiny Add-on, which work was so hard to do , but maybe think about the time Ziggy has needed to make this great IDE. As soon as I have time (next week or so) I will buy this add-on, not because I didn't know other ways to do it, just to honor the work Ziggy has done so far.
