My husband just texted me saying he noticed this on his new iPad Pro, too and asked me if I'd read any forum comments about it. I'll pass along your comment to him.I have to amend my previous review a bit as I’ve noticed major RAM management problems. iOS 11 seems to have a lot of trouble keeping apps loaded in the background. A lot worse than 10.3.3.
I was originally going to update iPads first and phone last but ended up just doing an update of my iphone 7 Plus so I can get my Apple Watch updated soon. There are a few apps acting occasionally a bit buggy and slow to open. Mostly it's my battery life taking a hit. I like the new Control Panel. The font looks babyish and it all looks preschool bookish to me, but I can see it with middle aged eyes, so I guess it's okay.
