CoolStrip is a single-level vertical menu of links with a 'sliding' feel. Each menu item links to a different URL, and an unlimited number of entries can be included. CoolStrip has a variety of user-feedback options. Menu entries can react to the mouse by changing color; a selector can highlight the focused entry; a scrolling arrow can follow the mouse up and down the menu; an image can be displayed above the menu for each entry; sounds can be specified.
