I had asked this question awhile ago, but to add on, wouldn't it be nice to know what the connected users are listening to?
Another thing I found out is that they might be connected but they might not be listening. Like clicking on the shared library icon connects you allows you to access their library, which tells the other person you are connected but not listening
I think they should upgrade the feature in preferences to let you know, How many are connected and how many are listening. At work I will leave my computer on if someone is connected
