It's really hard to get the overall context of a workflow. It would be nice to have a list tasks that I am assigned to in the case and that I get a preview of what is coming next.
When you open a task, you'll find a list of all tasks on the left hand side. There you can also see the assignment. Is is that what you were initially looking for?
Alternatively you could also go to Tasks > All tasks and then apply whatever filter fits your need.
