Springdale 7 by default gives you four different workspaces to use and are shown in the bottom right corner.
Create more or less workspaces:
- Hit the applications drop down in the top left corner
- Scroll down to Utilities
- Click "Tweak Tool"
Once the tweak tool window opens click on workspaces at the bottom.
By hitting the '+' & '-' symbols will generate more workspaces for you.
