The Task Manager is great, but it can get overwhelming if you have a number of individual tasks and a few workflows going.

Possible solutions:

Toggle workflow view.
(so you can only see tasks that DONT belong in a workflow.)

Collapse Workflows.
Include a collapse button on Workflow cards. When pressed all tasks associated with that workflow disappear except for the one you clicked (which then turns a different color or has a big "+" in the title so you know there are associated tasks.
