Kodi (formerly XBMC) is a popular option for those who want to roll their own media center, and the official Kodi remote "Kore" plugs into the system perfectly. This app hit the Play Store earlier this year, shortly after the alpha and beta builds of Kodi did, and now Kore is getting a nice v2.0 update.
Here's the changelog for v2.0 of Kore.
- PVR/Live TV support
- New animations on transitions from list to details screens
- Added option to play/queue entire album, artist or genre
- Improve library syncing
- Various tweaks
- Bug fixes
Kodi is more than just an app with playback buttons. You can control playback, sure, but it also has access to the playlist, subtitle sync, audio streams, window modes, and more. As of this update, Kore can be used to control live TV and PVR/DVR functionality, assuming you have that enabled in your Kodi installation. The use of animations is more extensive now, but Kore is a material app so it's not like it had no animations before. The "various tweaks" above include things like YouTube video access, better add-on support, and more. Check the Kodi site for full details.
