I'm trying to find original sources, as my memory is a little foggy. There is some good information here: https://en.wikibooks.org/wiki/Oberon/ETH_Oberon/Tutorial https://en.wikibooks.org/wiki/Oberon/ETH_Oberon/Tutorial Basically it combined a nice Model-View-Controller widget collection with facilities like live introspection and editing of widgets, and embedding widgets in (multiple) documents (edit a spline widget in one view and it changes in all the views/docs in which it's embedded) It might sound a little plain vanilla now, but this was in 1990-1991.
