If there is text within the shapes, both the shape and text moves as one unit, saving you from moving the shapes and text as separate elements. There are, also, diagramming programs, that have make drawing simple geometric shapes easier to do and easier to move around and esier to edit and change their appaerance. What type of diagrams are you drawing/painting? So, there's the quick tutorial about layers. You can, also, more easily move elements around on a layer more easily that having all the elements on a drawing or painting on one layer. If you don't alike what you did on a layer, you can erase an entire layer and start drawing or painting on that layer, again, or delete the layer entirely. If you want to alter elements on a layer only that layer gets affected. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications.
Pre-2007 versions of Excel use XLS as the primary format for saving files. You can build up a drawing or painting by putting different elements on different layers. Microsoft Excel is a commercial spreadsheet application written and distributed by Microsoft for Microsoft Windows and Mac OS X. Think of layers as multiple sheet of clear paper or thin sheets of clear plastic that you can draw or paint on. Why are you afraid of applications that use layers? Layers are one of the easier concepts of both drawing and painting apps to understand and use.
