I don't understand why they've hidden friends/messages/notifications under another button click. It's so dumb. When I go to the friends tab, I want to see my friends straight away. This new change is genuinely ridiculous. I can't see how anyone thought this was a good idea.
The ads on the home screen are annoying as well. Suggested Friends, no matter how much Mike Ybarra/Larry Hyrb/Phil Spencer/whoever defends it, is stupid. I haven't heard one single person say, "Hey, I use this! It's great!" Stop shoving it in my face. If you insist on leaving it there, give me the option to turn it off.
There's wasted space EVERYWHERE, especially in the guide (because of everything being hidden behind an extra click, for no apparent reason).
I'm not happy that we're now limited to 18 pins.
I've only had an Xbox long enough to experience one new dashboard, and it was a really good improvement. This one, so far, is a big step back. For now, I still have faith that they'll bring it around.
