It would be very helpful if, when I receive a message and the window is not in focus, that I receive a notification and/or a red notification badge on the app. (I don't know if non-Mac systems have badges.)
When I messaged my counselor about something and she didn't see it for a while, she also said it would be nice if they made a sound - that can be a good temporary fix if making notifications is complicated.
Thank you so much!
