Signal the presence of unread messages in a Circle
When unread messages are present in a Circle, the user should have a visual signal letting him know someone talked in the Circle since the last time they visited it.
There is no such thing in the mockups, but maybe making the Circle's name bold is enough. Confirm with @sophie
I'm sorry to add that item, I thought it was on the radar already. To me it is the last missing peace to have the chat really usable in desktop. Next is mobile so we don't have to default to Telegram and Whatsapp all the time.
