ShideWin is a very, very small program with a very, very great impact. On the first sight, its simplicity is incredible: it has only one window, with only one list (no buttons, no toolbars) the list of all windows currently open on your desktop (only the «main», top-level windows). By selecting or deselecting items of the list, you hide or show the corresponding windows; by hitting ESC you exit. Thats (nearly) all.
Such a simple, fast, useful thing has many possible uses in a geeky environment. ShideWin can be used as kinda «punish button», when a «more colorful» way of enabling windows, like the tray, virtual desktop or other goody, is broken. Other than that, you can treat ShideWin as a spartan windows management solution to keep your desktop highly organized by easily hiding unnecessary windows (without closing the applications). Finally, ShideWin is a lightweight windows analyzing tool used for quick tasks, when using something more complicated (and, of course, demanding heavier CPU and memory load), like Spy++, is inappropriate.
ShideWin basically shows, how the simple idea about the functional minimalism can be taken right. Its a common characteristic of tools working with the most general idea in their environment. (In Microsoft Windows environment, one of most general concepts is evidently windows themselves.)
