Chord Edits Compare and UpVote

There's really a lot of potential to be had for the Chord Edits.

One thing would be Compare Edits. I'd like to know what was changed between my Edit and the Original. By the way, does Chordify update the Original over time as your AI improves?

Another thing would be Edit Voting. I'd like to be able to vote that an Edit was good, and also checkout the most popular Edit.

A third thing - This may be a little technically difficult but if you know of BandLab or GitHub source control, which allows anyone to create their own versions based on an original copy. So basically, Edit Versioning or Edit Layering off an existing Edit or an Original.
