show it user status is on mobile
It would be great to see a status/presence of when a user is signed in only on their mobile. It helps other users to realize if the person they are contacting may have a delay in responding because they may not see the details on their mobile (perhaps they are driving).

If implemented, this should be optional. I often work on a mobile device, and I would not want a mobile icon to deter colleagues from contacting me.

This is also very relevant for globally distributed teams. It is very unfortunate to participate in a persistent chat, only to realize you caused someone's phone to be very noisy at 3am. That's a great way to encourage staff to hate the application (e.g., Teams).
