Among the features currently being worked on for GNOME 3.8 include:
- Porting GNOME Shell to use X Input 2 (Xi2) as it's needed for multi-touch and gestures handling.
- Integrated application search within the GNOME Shell by allowing applications to be "search providers."
- Improvements to GNOME Clocks.
- Notification filtering within the GNOME Shell.
- Integrating ownCloud into GNOME for having your own cloud service, similar to KDE.
- Implementing a UI for color tinting support within the GNOME Shell.
- User-interface improvements to GNOME's Totem video player.
- Evolution should support Ubuntu's single sign-on (SSO) framework, finish migrating to WebKit/GTK+, remove the legacy IMAP back-end, and provide a new importer framework.
- The Epiphany web-browser should have various user-interface enhancements, getting WebKit2 support merged, and have new back-end functionality.
- Frame synchronization support for GTK+ and the Mutter compositor.
Many of these upcoming GNOME features are outlined from the GNOME Live Roadmap Wiki.
Further out on the horizon is GNOME 4.0 and the GNOME OS.
