The Oberon user interface inspired Acme on Plan 9.

Oberon is a very nice, fun and cozy system and environment for programming. I lived in it for a few months back around 2010 and it was a joy.

I often think this style of UI -- tiled text windows but with mouse and graphics interaction (similar to emacs actually) -- is what we should be using for the coding agents we're all using now.

I'd like to be able to dock panels of information, live-edit pieces of code instead of just "accept? Y/N", have side interactions, have real scroll bars and proper clipboards, even a live REPL alongside.

Instead we get Claude Code's janky "60fps TUI" full of bugs and barely interactive.
