As we developed the Motion Control API (MCAPI) and the many application programs we provide that use the MCAPI, our programmers found they were constantly re-using common bits of code. Bits like setup dialogs for servo and stepper motors, or handy functions that save axis settings to a file or restore axis settings from a file, and dialog boxes that allow the user to select a motion controller from all the controllers currently installed in a PC.

So we figured if they're useful to us they might just be useful to our customers. The result is the Motion Dialog library, a set of user interface functions and dialogs that are pre-built, tested, and ready to run.
