Among the many "wish list" features were document-like resizable and scrollable windows, 8-bit color support, and the ability to display and work with graphics files stored externally.
Plus did not, however, provide for pull-down menu support or allow stacks to be compiled into stand-alone applications, features of the competing Supercard.
These versions used the same file format as the original, meaning it was the only HyperCard clone of the era that allowed a single stack to be used on all supported platforms.
The system was later purchased by the newly formed ObjectPlus in early 1994, dropping the Mac and OS/2 versions and releasing the greatly updated WinPlus 3.0 in 1994, and 3.1 in 1995.
It was first introduced in 1991 as part of "Oracle for Windows", which included a full suite of client/server software and a variety of their existing database client-side interface programs (text based).
