This looks really great at first glance, thanks for doing all the work to fix formatting and make this all look better and more readable!

I will try to test it in the next day or two and give you any more feedback. One thing to note though, some of the excessive string formatting was because of special characters like smart-quotes that sometimes seemed to through the TTS for a loop. I'll try to find some examples that were problematic in the past and see if they still have issues with this branch.

Thanks again though, I really appreciate you taking the time to submit this!

Just needs one change - bump the version number in setup.py and I'm happy to merge this. Thank you again!!
