This includes such features as FastStart for games (SOME games, not all), Games and Apps grouping, Search Option feature additions, Mixer Share Controller improvements, and console broadcasting and stability improvements. All players have to do is simply click download on selected titles, with the system doing the rest, so it seems like FastStart will be fairly easy to use.

What's essentially FOLDERS have been added to the Xbox One universe. Multi-touch was added, so multiple controls can be used at the same time. Each channel also now features leaderboards, showing who contributed the most. Since entering Xbox Game Preview, Darwin Project has also gained a Duo mode, private matches, a Glider tool, skill-based matchmaking, five new Show Director powers, and support for eight different languages. This is what differentiates it from the existing Ready to Start feature - that allowed players to launch games before they were fully downloaded, but required developers to manually section off required data.
