Good Start...

Has potential, but not ready to replace metaX.

1. There is no indication that the tagging update completed.
2. Would like to see a "create copy before updating" feature.
3. Since Apple refuses to let the user see any tags (other than what they think you need to see), this app needs additional fields. IE: I use Album tag for directors.
4. Would like to see an IMDB or TMDB pop up window for when TMDB does not find the movie. I know, I can have a seperate browser window open.

Overall, a good start.
