Apple should have just replaced the "Missed" panel with a "Dashboard" or "Wdigets" panel. A dedicated widgets panel would have made more sense.
There are going to be way too many widgets lined up one after another. It's going to be too busy.
I totally agree with this. They definitely need to separate notification messages away from these widgets. For the most part I can't see a reason why they would need to exist together. A separate Widget area would have been better and maybe we will get that eventually. At the very least you should be able to "stack" all the widgets together and then "messages".
