I've been exploring @kagihq's Orion browser for a bit now. Judging from the overall #UX, I'm beginning to think that Orion is a better (fully #macOS-native) browser than Safari.
E.g., Safari shows bookmarks in a browser window, and it closes all folders every time you close the window. Orion has a dedicated bookmarks window and remembers all folders’ open/closed states across launches.
There are plenty #IxD details like this one, whose design in Orion simply is superior to Safari’s. Well done!
