Awesome changes @jayhogan, I'll take a better look on Monday. Could you please back out the changes to the built files, they are not needed for pulls.

This pull request looks like it is done from you master branch. Could you please make a feature branch and do the Repeat mode change in there?

Usually what you should do is create a feature branch from your master, implement the feature and submit the PR. When the PR is accepted and merged into the main repo's master branch you pull from the main repo to update your master (and delete your feature branch if you want). This way the people who are maintaining the repo you sent the PR to, can pick and choose PR's.

Cheers :)
