Since One UI 7.0 the Bluetooth icon in the status bar is gone. Before that an active Bluetooth connection was directly visible which is extremely helpful if you have to switch your headset between smartphone and computer. Now you have to swipe down to open the notification area. This is an unnecessary functional deterioration.

Please bring back the formerly perfect behavior of the status bar.

[EDIT:] … and if there have even more icons disappeared: please allow all icons to appear in the status bar with QuickStar (Good Lock) to be shown and prioritized. QuickStar does not distinguish between "Bluetooth" and "Bluetooth with active connection". Adding this would be the best solution.
