In many ways, the Lisa is more sophisticated than our current GUIs. In particular, I liked the way applications meshed into the system and disappeared into stationery - if you want to create a document, double click on its corresponding stationery stack and a new document is created. No need to find open Excel (or LisaCalc).

IIRC, Windows 95 briefly had this in the form of a Templates folder. You added files to that folder and then you could create new copies of those files from the context menu. I don't remember it persisting into other versions of Windows.
