Decors are a means of managing the abundance of visual appearance options for windows. In the original Fvwm code, there were many options that could only be set globally, although they affected window appearance. Decors are a compromise between leaving them global and making them fully settable per window. These quasi-global options may be set in a particular decor, and a decor may be attached to one or more windows. Having to use decors to change certain aspects of the look and feel is confusing. Scwm will probably move to some way of making these options directly settable per-window at some point, especially if we can figure out a way to not increase the memory overhead much.
