Here's the changelog for version 3.6.1272:
- Easily find movies and TV shows similar to the ones you love, right in the app
- Better keyboard and mouse shortcuts for full-screen playback
- Bonus content purchased with a movie is now shown on that movie's detail page. No more extras cluttering up your gallery!
One of the new shortcuts is the ability to (finally) toggle full-screen mode by double-tapping on a movie. Subtitle support is still inadequate, but with Microsoft adding new features constantly, we'll likely see better compatibility for subtitles in future updates.
