I'm assuming this is for Remote Desktop Beta for Mac. Sorry if it's mis-classified but there is no indication what this forum is. I believe there used to be green dots next to active Remote sessions, but that seems to have disappeared in the latest version or 2. Very helpful to see what remote desktops have a session active. The green dot was perfect, and the red for non-gracefully disconnected servers was handy as well. Not sure why that went away. Looked through preferences to see if it was set-able. But don't see that. I'd consider it a great idea to put that feature back in.
