The Eject Volumes tool is great, but as there is no visible confirmation that all of the desired volumes have been ejected (as per the configuration), another application (Finder, Terminal, etc.) just be used to check for the completion to avoid disconnection alert. For me, mostly this is a Time Machine backup drive connected to by USB-C hub, which I don't like disconnecting incorrectly. Could the menubar icon change colour, flash, or something upon completion?
