I am using Xfce desktop on Ubuntu 18.04-based system.
I can easily switch connected audio output devices between them (including bluetooth ones) with a Xfce panel plugin, but when bluetooth speakers are not already connected I use
blueberry-tray to access and connect bluetooth devices.
I am using various bluetooth speakers with different computers and often the speakers are not connected automatically in Linux. Using
blueberry-tray is a bit cumbersome as it involves no less than 3 clicks and two opened windows.
blueberry-tray is a tray icon to start the
blueberry GUI, not really a tray tool - one that should provide all needed operations by itself without starting a separate GUI, with multiple windows, etc.
I wonder if there is a tray tool similar to Sound Switcher Indicator or the aforementioned Xfce panel plugin, only not for switching connected devices, but for connecting/disconnecting available (already 'added'--associated) devices, notably bluetooth ones.
I mean something like the panel tool they have on a Mac, where you can click the icon, see all added devices - including non-connected ones -, and press 'connect' without opening any window.
