I downloaded 14.0.1 last night. Other than the widgets, I don’t see much difference so far. I had my apps organized into groups anyway (aside from some constantly-used ones), so the App Library thing doesn’t really matter to me. The weather widget is nice. I notice it appears you have to push it all the way to one side or the other—seems like you can’t put it in the middle with app icons to either side.
Same here. Pinning text chats is nice but that’s about it so far.
