WorkShelf is part of Winstep Xtreme, a powerful suite of User Interface replacement applications that merge incredible usability and performance with breathtaking eye candy!
NeXuS is the Dock system, and is just perfect for super fast access to your most used applications. You can have as many docks as you want, and each can have multiple sub-docks! When not in use, docks can hide behind your screen edges, taking virtually no screen space.
WorkShelf is a tabbed dock, better suited to complex organizational duties like organizing documents, URLs, movies, work projects, etc... If a dock is the top of your desk, then Workshelf is all the Drawers below it.
NextSTART is the menu system - and takes care of all your task management needs as well. Menus are great for accessing infrequently used files and system related commands that aren't easily reachable in the file system or that have no readily user-recognizable graphic representation.
