Classification
Windows managers can be dynamic, stacking, or tiling in their behavior. Stacking window managers behave analogously to pieces of paper on a physical desktop, they can be stacked on top of one another, with the one at the top of the stack being the one with which the user sees and interacts. Tiling window managers represent windows as tiles, or split views, with windows displayed next to one another, but with none of the windows overlapping. Dynamic window managers are window managers that can dynamically switch between these two paradigms.
