Custom Color for YouTube's Progress Bar

Works great. Is it possible to add a thickness adjustment to the bar? I understand if that is beyond the scope of your extension. I'm using Enhancer for YouTube as well. There is a script box that I could put a code in to probably do this. I just don't know how to do the coding. I'd really like to be able to make the progress bar twice as thick. Thank you.

rly neat little extension, easy to use too

cool

You guys are the best, the perfect complement, all in one. Thank you very much!

Works like a charm, highly recommended, liking my new blue progress bar

I'm surprised this doesn't have more downloads

Great extension, but it lacks the option to change the HD button color
