In the dashboard list widgets, there is an option to show the breadcrumbs of the task. Right now this only shows the hierarchy (space/folder/list) and excludes the parent task name when the task showing is a subtask.
This is a necessary part of the breadcrumbs/hierarchy. Frequently you will find that a parent task will have a client name and subtasks will not due to redundancy.
I think this just makes sense to be included in the existing show breadcrumbs feature (similar to the "show task locations" toggle on the home view.) But at minimum, there needs to be an additional toggle to show the parent name, like there is in views.
Also, I would like to have the option to toggle this setting for the new feature where when you click a calculation, chart, etc and it shows the list of tasks being attributed to that data. (But the list widget is higher priority.)
