The Budgie Control Center doesn't appear anymore in the list of the apps on the Menubar.
I don't know since when, just today I wanted to check the resolution of the 2 monitors that I use and I wasn't able to start the BCC from the menu. Anyway, the application is there because I was able to access it from the menu of the Bluetooth.
In general, none of the 'apps' that are in the BCC are anymore visible in the menu.
