CoolStrip is a vertical Flash menu applet. Each menu item links to a different URL, and an unlimited number of items can be included.
Menu items can react to mouse hover and click by changing color; a selector-bar 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 item; all colors, fonts, spacing and alignment are customizable. CoolStrip can be transparent and supports sound effects.
Colors, fonts, styles and behavior are fully customizable, either using the free Cool Focus Design Studio or by following the instructions in the documentation.
