 The next thing I'll talk about is Layers.  The Layers panel lies tucked to the side but can be clicked or dragged open at any time.  Layers work very much like they do in other drawing programs: you can create new layers, rename them, change the order and delete them.  Elements not on the current layer are not selectable, so it's an excellent way to separate elements in your drawing so that you can work on them without interfering with other parts of the drawing.  If you want to move elements between layers, select them, then select the layer you want to move them to.
 
 There are a couple of other minor features that round out SVG-edit 2.4:
-	* It is now possible to embed raster images (via URL) into the canvas using the Image tool on the left
-	* It is also possible to keep the ratio of any element fixed when resizing by holding down the shift key.
-	* Finally, if the canvas is starting to become obscured, you can turn on 'wireframe mode' which shows the outline of all shapes in your drawing, but none of the fill or stroke properties.
