Looks like what I've been building is quite similar to what the foundation of Patchwork-26 is. Lots of "tiny apps" (atomization of software, loosely coupled) + just the web. Local-first and where everything revolves around the content (data-first, can use preferred UI/view). Happy to see this! 🎉

Microsoft has been testing 'Olympia' windows in Edge for months now; I still don't know exactly what the purpose of these windows is, but something interesting is that in Canary, these windows have a new UI with floating tabs 🤷:https://t.co/UMcY00v70w pic.twitter.com/GGb7XT8uEG— Leopeva64 (@Leopeva64) July 30, 2025

Smalltalk
Smalltalk is a purely object-oriented programming language that was originally created in the 1970s for educational use, specifically for constructionist learning, but later found use in business. It was created at Xerox PARC by Learning Research Group (LRG) scientists, including Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Diana Merry, and Scott Wallace.
