Task Counter/Number of Tasks

It’s not really wanting to see how many tasks a client has (as it’s possible to see this by going to the client, and then tasks) I want to be able to see the number of due/overdue task that I have…. And I also want to be able to see what each team member has in terms of the amount. Right now, unless I count them, I can’t see easily how many tasks me or any team member has.
