I will have to try this out when I get the free time! I’ve been periodically checking on the GNUstep ecosystem since 2004, and this is the most exciting development I’ve seen since Étoilé from the late 2000s. Judging by the screenshots, the desktop appears to be Mac-like while also not being an exact clone. If this desktop takes off, maybe we’ll finally see an ecosystem of applications that use GNUstep instead of GTK…
I’m working on something similar for Linux. Would love to chat if this is interesting to you. The idea is to bring the UX of OSX Snow Leopard back, adjusted for today’s possibilities (better developer experience, AI, etc.). I’m developing a DE, SwiftUI/AppKit-equivalent, and a bunch of reference apps I‘m personally missing in terms of quality (e.g. Raycast/Spotlight, Mail).
You would want to adjust it for today's display and input technologies. A high resolution OLED display deserves a different UI design than a 6-bit low-contrast TN LCD display did.
