There doesn't seem to be a notification to indicate how many unread chat other than the grey numerical label on the unread chat itself.
I would have thought the bell button on the top right would indicate to me all the notifications today - which would be helpful but turns out that was only internal updates about sleekflow.
Reason I'm pointing this out is because I missed few messages from clients yesterday as there were too many and those unread msg got pushed to the bottom of the chat list.
So what I am asking for is really 2 things:
1) better reminder of unread messages, a function where i can just click to see unread msg?
2) better notification display of who chatted with me today, etc. similar to the notification list you will see on facebook or instagram
