Yes right, i can add bluetooth widget, wasnt aware of that. Would be useful if i could also add wifi or airdrop widget
You CAN add a Wi-fi widget. And while there's not a native airdrop widget, you can add a Shortcut widget that controls airdrop.
(edit: spelling of Wi-fi)
You can fully customize the Control Center. If you want BT devices on the first page, put them there. Also, you can do a longer swipe to get several pages deep, instead of a swipe a tap.
I’ve noticed some bugs, but I assume those will be worked out in time, just like with any major release.
