Owen Taylor has written another GNOME Shell status report. Here's a short version of his post:
The most obvious change visible here since my last post are workspaces. As you add and remove workspaces they slide in and off the screen with a slick animation. Marina added the recent documents section to the sidebar with the appropriate thumbnails. Marinas also working on adding the ability to expand the sidebar sections to the full screen so you can browse More applications or files.
Colin added a user menu to the right side of the panel, so now you can actually log out, switch users, etc, from within gnome-shell.
Colin also did a quick hack to get the current GNOME taskbar to show up at the bottom of the screen. We’d like to do something better, or at least visually slicker, in the long term, but this fills in a big hole in the ability to just use GNOME shell day-to-day.
There’s some more interesting work in the pipeline - enhancements to the “More” views, monitoring the applications that the user is using and so forth. See our Todo for ideas about ways you could help, or join us on IRC in #gnome-shell and ask questions.
