That will be great for Gnome3 extensions too. Although they are great and there are some very useful ones, I have this feeling that a few of them look a bit abandoned. There's much potential there to be explored.

By the way, I miss a few functionalities from Gnome2 in Gnome3. These extensions make it complete for me.

- [AlternateTab][1]. I can't get used to grouping windows by application. It requires one extra step to get to a target window. I think workspaces do a better job for organizing windows.

- [WorkspaceGrid][2]. I like this way workspaces are organized better than a single line. Makes them more accessible in a 4x4 setup.

- [TaskBar][3]. I miss the task bar from Gnome2. I still use 'Activities', but it requires one extra step to get to a window. It's great for having an overview of your applications, though. I enable a single taskbar at the top.

- [PixelSaver][4]. Remove the title bar and blends the close button with the task bar. Saves a few pixels when the window is maximized.
