VisualWorks had one notable cross platform development feature in that it could mimic the look and feel of the other operating systems it supported from any of their platforms, so you could design your program on OS/2 and test how it would function on Motif or Windows.

After the merger of VisualWorks developer ParcPlace Systems and Digitalk a version of VW was released under the name VisualWave that integrated the development system with Smalltalk libraries developed by Digitalk. These included mainly web development tools but also a host of others, and existing VisualWorks customers could buy it as an upgrade. While this package could develop for OS/2 as a target, it is not certain if a native OS/2 hosted version was ever shipped.

The VisualWorks product product line was acquired by Cincom in 1999 who have sold and developed it since, although active development has slowed down considerably as the company places more emphasis on their own in house developed Smalltalk system for MS Windows.
