About the Layers Group
 This area is the layer management area. On left side of the group there is a thumbnail of the the current layer you are working on. You may add a new layer by moving your mouse to the "Layer Options" link and select the Add New Layer option from the popup menu, you may also may make certain layers invisible or send them to the back of the rendering order, as well as being able to change the rotation of the layer or flip it around horizontally or vertically. To select the layer to work on, move the mouse to the area that would originally read "Background", a list will popup with thumbnails of the layers, here is where you select the current layer to work on.
