"Quitting" the Logi Options+ app on Mac, using either the keyboard shortcut ⌘+Q or the menu bar item, does not quit the app. These actions close the active window, but the background processes remain active.

These actions appear to behave the same as "Close Window ⌘+W". It is generally accepted that background processes will remain if the window is closed, but will be killed if the app is quit, given that two options are provided.

At the moment, to kill the app, I must quit through Activity Monitor, but I would expect that this behaviour can be reached through the main app.
