Current problem
Seeing an alternate instance notification is only really visible via the push notification / desktop notification. There is a lack of visual indicator for this when the app is at rest (not clicked into the account switcher where the current notification bubble is).
Proposed change
It would be cool to see a notification bubble that displays the cumulative number of all notifications across logged-in instances on the corner of the user's profile picture on the bottom left (similarly to how a server shows notification count), as that is used to access the switcher to discover which instance gave the ping.
