Once thing that's a bit annoying is that they've put the command center in order of 1, 2, 3 from when you first swipe up.
So to get to the Home Automation scenes you need to swipe up, then right twice.
They should have put music on the left and homekit on the right, so you only have to make one sideways swipe no matter which one you're after.
Quite annoying that, as I was hoping to be able to free up prime above the fold widget space on the widgets screen. But 3 swipes is a lot more cumbersome than 1, when it doesn't need to be like that.
