→Sugar changes
With the SWF content viewer to base on, a Flash developer can develop a game in Flash but use Python to add toolbars and GTK widgets. They would package their Python code and SWF file in a Unified bundle, and subclass the sugar-swf-activity classes in their Python code.

==Sugar changes==
==Implementation==
The primary change to Sugar is that it should gracefully handle failure to find the program specified by the 'exec' line in activity.info, displaying a friendly error message on the launcher screen to the effect of "You do not have the required software to view this content.".

There is also the new hidden=true line in activity.info to prevent Content Viewers from appearing in the Home view.

Most of the work is in converting existing activities to Content Viewer packages, packaging them and writing the sugar-xxx-activity wrapper scripts. Fortunately, this work can be done one content viewer at a time and the old and new systems can coexist.
For example, you can have Read and sugar-pdf-content-viewer installed simultaneously. The user will be allowed to open a PDF file with either, and sugar-pdf-content-viewer will only come into play when a Unified bundle is opened.
