Modified version

[Intrinsically-Sublime]

I created a modified version with a bunch of changes. https://github.com/Intrinsically-Sublime/harmonize

Feel free to implement any of the changes if you like them. I did not commit them as individual changes so they will need to be cherry picked.

Also I do not know python so I may have done things terribly, so any suggestions are welcome.
