[1] Appleton combined elements from World Builder (that he wrote), HyperCard, SuperPaint and the Macintosh user interface.

[5] Also, this version introduced an application called Standalone Maker, which put a front end on the ability to edit the resource fork of executable SuperCard projects.

SuperCard had always been able to produce stand alone executable applications, but this tool lowered the barrier to entry for novice users.

This add-on allowed projects to communicate over local networks or the Internet, offering server-side functionality and foreshadowing the robust web application era of today.

The first was a true "port" of the product (which would have included both editing and runtime environments on Windows), but it was taking too long and was very unstable due to the lack of a robust graphical "toolbox" such as the one offered on the Mac platform.

This new version introduced Mac OS X support, complete theme compliance and a wide range of user interface elements to go with it.

[12] As a result of the passing of Scott Simon, co-owner of Solutions Etcetera, in April 2024, the SuperCard web site and that of its parent company were taken down.

The clear turning point in SuperCard's commercial viability was Solutions Etcetera's decision not to follow Apple's development roadmap.

This, combined with the rise of competing, more modern, cross-platform authoring alternatives and frameworks (e.g., LiveCode, Ionic_(mobile_app_framework)) vastly diminished the potential customer base.
