NeXTSTEP 4.0 Alpha; sometimes mis-called Beta on web sites.
The software featured tabs across the screen bottom for various window types. (We cribbed these for Mac OS 8.5 after the merger, as the tabbed window feature.) The Documents tab was a window which presented icons of documents, each of which could be a preview of the actual document, badged to indicate the associated application.
This implementation nicely meets all the claims, but predates the patent application by 5 years. I won't bother going through all the details, but Cygnus is boned. Software patent litigation as a business model is so last decade...
