Have a "I'm working on this" or "currently doing this task" ticker

Hello,

I have been thinking of a design, just a little ticker on tasks or a heads up within those.
this could be helpful if time is being monitored or participation of a team.

this little nuance in design can be helpful for us remote teams working on the other side of the globe knows that we are doing the task or have we seen the task or slacked off.

Thank You
