Wow, yesterday I got my 4th Daily Deviation, for GNOME-Shell - Google + theme [link]
Sorry to GNOME-Shell users, I don't update the themes any more, since I don't use GNOME now days. The good thing is that it's GPL, so anyone can update it.
Plasma Workspaces have been refined considerably. Work continues on updating widgets with new ones built with Qt Quick. This effort brings improvements in consistency, layout behavior, stability, ease of use and performance. It is also now easier to build widgets, entirely new Plasma Workspace layouts and other custom enhancements. A new QML-based screen locker makes Workspaces more secure. The wallpaper engine was also updated to QML, so it is easier to write animated wallpapers. (QML is part of the Qt Quick application framework.)
In addition to improvements related to Qt Quick and QML, the task widget received some usability updates, with a smoother look for groups of windows. There also have been improvements to the notifications system, particularly in the area of power management. There is now improved support for high resolution displays and a new Air theme reducing visual clutter and giving Plasma Workspaces a cleaner appearance.
