Wow, this is excellent. The Oberon and Bluebottle OS materials have always been quite scattered, so someone putting them in a central index is quite convenient.
For those unaware, Oberon's main qualities are the fact that it's a full operating system written in a garbage collected Pascal-like language (actually made by the same person who initially wrote Pascal) which uses said language's module system to provide reusable/chainable interfaces throughout the whole OS, support for orthogonal persistence and most notably, its highly unconventional user interface that bridges the power of the CLI and the GUI together in this vaguely hypertext-like workspace where you can dynamically live program the UI itself through on-screen text that can serve as an entry point or continuation to perform all sorts of computations, things you'd normally write hacky scripts for. Closest analogue is Xerox's Cedar.
You should consider trying it and stealing a few ideas from it for the greater good.
