I uploaded a new version already. It's available at:

I fixed a few minor bugs that were introduced as I cleaned up the code for release.

The main issue that this update fixes is that the "Commit" option of the Batch Update Tool wasn't working. That's fixed now.

To upgrade just extract the archived files and copy them into your store's folder so that they overwrite the existing files.
