Settings:		~/config/settings/system/app_server/workspaces ~/config/settings/Backgrounds settings - stores the panel's window position

You can set a color or an image as background for every folder and the Desktop for every workspace.

The top menu specifies if your changes are applied to the current workspace only, all workspaces, a specific folder or as default for every new folder.

Below that you can assign an image or select None if you want simply a colored background. Images can also be drag & dropped onto the preview to the left.

If you are using an image, you have to decide on the placement:

Manual		lets you specify the coordinates. You can drag the picture around in the preview to the left or enter X and Y manually.
Center		centers the picture in the middle of the screen.
Scale to fit		enlarges the picture with no regard to its aspect ratio until it fills the screen.
Tile		fills the screen by repeating the picture.

Activating Icon label outline puts a thin contour around icon labels.

Whether an icon label's actual text is black or white depends on the setting of the color picker. A dark color sets the text to white, a light color to black. So, if you assign a very bright image to the background, you should also set the color picker to a bright color in order to have icon labels readable in black. (Or use the outline option above.)
The selected color is also reflected in the Workspaces applet, which ignores images as backgrounds.

Revert		brings back the settings that were active when you started the Backgrounds preferences.
Apply		sets your changes.
