It can add a drop shadow to windows, change the Clear Type contrast, change a visual style's color or the wallpaper and much more ...
But its most useful function is located in the "Styler Toolbar" which can entirely change the look and feel of the Windows XP toolbar. So you can change your toolbar to make it look like
Windows Vista's or Mac OSX's ones.Styler doesn't use so much memory (less than 1MB when is used in the background).
You can simply create your personal Styler toolbar, or modify the parameters of any existing toolbar, by opening its config.txt file.
Many of the windows xp visual styles include a Styler toolbar, so this program is actually a "must have".
