You're probably familiar with the "Always on Top" feature of some programs. This allows their window to "float" above other windows even when it doesn't have the focus. This can be extremely useful. Unfortunately, not many programs implement this feature. TurboTop is designed to remedy that problem!
TurboTop is a little tool which will sit in the systray. By clicking on the TurboTop icon, you'll be presented with a menu that displays all windows that are currently visible.
Simply click on the menu item that corresponds to the window you want to make "Always on Top." The popup menu also shows which windows are currently "Always on Top" by displaying a check mark next to the name of the window. When you click on a checked menu item, TurboTop will make that window not "Always on Top."
