Having used this for a few days now I have to say it's a great improvement but it's just still so complicated compared to windows. It's great that they've added visual indicators for most of the gestures but:
- they added Quick Note, which is hard to discover and only works for certain apps
- Slide over still feels a bit mysterious to trigger, but it does at least show when it's hidden again.
- The shelf is just another concept to learn.
- The centred modal view is handy, but again is just another specific case to learn.
I feel like they're introducing very specific windowed situations (e.g. Quick Note if the app supports it and if you drag from the bottom right) and I think it could still be much simpler, but I guess there's OS limitations in the way.
