Thanks. It's good to hear these experiences.

Re: UI customization - I realized that I hardly customize my UI anymore, so I don't think I'd miss that. There were times I had all kinds of crazy setups with alternative launchers, but I've been sticking with the standard Pixel launcher for years now.

I've been looking into some of the Focus functionality, and it looks interesting. It wouldn't meet all of my notification needs, but it might be enough. Mostly, I think I'd have to change my expectations if I were to move to iOS. We'll see.
