XWorkplace's XCenter supports plug-in DLLs, so people can write new widget classes without having to work on the actual XWorkplace source code.

A number of people have taken this opportunity already, and the list of third-party widget classes is growing.

Steve Wendt has produced a very nice list of XCenter widgets, so if you like the XCenter, you might want to take a look at it:
