What is a workspace, and how will it help me?
Workspaces refer to the grouping of windows on your desktop. You can create multiple workspaces, which act like virtual desktops. Workspaces are meant to reduce clutter and make the desktop easier to navigate.
Workspaces can be used to organize your work. For example, you could have all your communication windows, such as e-mail and your chat program, on one workspace, and the work you are doing on a different workspace. Your music manager could be on a third workspace.
Using workspaces:
In the Activities overview, move your cursor to the right-most side of the screen.
A vertical panel will expand showing workspaces in use, plus an empty workspace. This is the workspace selector.
To add a workspace, drag and drop a window from an existing workspace onto the empty workspace in the workspace selector. This workspace now contains the window you have dropped, and a new empty workspace will appear below it.
To remove a workspace, simply close all of its windows or move them to other workspaces.
There is always at least one workspace.
