Mousetuary is a Kodi skin, derived from the Kodi default skin "Estuary"
The aim of Mousetuary is to make a Kodi skin that is a bit more mouse-friendly, for those who prefer to control a 10-foot HTPC interface with just a mouse. It also aims to take UI cues from Windows Media Center.
There are working krypton and leia branches, but as of the release of Leia, any new development will probably only be done on the leia branch unless specially requested or a showstopping bug.
