Microsoft posted an image with the, and it reveals a cog icon which will pop-up a dedicated section for Quick Action buttons i.e. Tablet Mode, Airplane Mode, Wifi, brightness control, etc. When in this mode, the action center will become purely notification panel giving out more space for those who keep getting tons of that.
That said, at least till now, Microsoft doesn’t seem to be forcing this, but testing with an option where the user can choose to either merge both of them or use them separately.
The idea is not new. If you are Android users, many phones come with a separate section for Notification Center and Quick Actions. Some of the phones do give the option to merge them as well. I would love to see the action center actually replicate the mobile style, or at least give an option to drag notifications from the top rather than from left.
That said, Microsoft can always cancel this or delay the feature for next update, just like what they did for My People for Creators Updates. Nevertheless, what do you think of this option?
