TL;DR - The bluetooth settings usually available in the upper-right corner menu (along with sound, battery, user profile, power off) is only present when bluetooth is turned on, but disappears when bluetooth is turned off.
I'm a pretty long-term Ubuntu user, and have been using Ubuntu 18.04 for about a year on two different laptops. I just got a new M.2 NVMe SSD for one of the laptops and performed a fresh install of Ubuntu 18.04 on there (I removed my SATA HDD for the time being and only have Ubuntu installed on this SSD - no dual booting).
I recently went to turn on the bluetooth to pair with my headphones, and looked for the bluetooth menu option from the upper right-corner menu. To my surprise it wasn't there (see image below).
Instead, I had to open my settings, navigate to bluetooth, and then turn it on. Once I had done that, the ability to turn off bluetooth or go to bluetooth settings was added back to the upper-right corner menu (see image below).
But once I turn off bluetooth, that option goes away again. Anyone encounter this and know how to keep the bluetooth settings in that upper-right corner menu? I'm not looking for blueman or an indicator along the top bar - I'm looking to just permanently keep the bluetooth settings accessible in the corner menu regardless of whether bluetooth is on or off.
For reference, here is a screenshot of the menu on my previous installation on my old HDD, showing that the bluetooth menu should still be there when bluetooth is off.
