Whats with all the buttons?!
The Buttons Window is one of the most powerful tools that Blender has. When you have objects selected in the 3D viewport, there will be a number of operations you can perform on the objects by pressing the buttons in the Buttons Window. For example, suppose you have modeled a person. People have different skin colors, eye colors, hair colors, and more, so you will create a material to make the person appear as you would like him or her to appear. The Buttons Window also handles sky color, render settings, animation, and a whole lot more.
