In the world of Windows, WorkShelf is the Swiss Army knife of User Interface enhancements. Intended as a multi-leveled desktop replacement, it is equally at home functioning as a tabbed program launcher. Like a dock, but better. It enables you to organize your most often used applications and documents into categorized shelves while taking as little screen space as possible: when not in use, it automatically collapses into a small strip of tabs.
NextSTART is a powerful, skinnable, and dynamic pop-up menuing system and task management utility that can be used as a replacement or supplement to the Windows Start Menu. NextStart also offers an incredible amount of flexibility so that the user can customize it to his needs and tastes.
