While using the "Group By" functionality in the Plan, given that the folders are expanded, we can see (for instance) how many Story Points were allocated to the parent work item, along with rolled-up values from the child work items.

However, if the view is collapsed (given the scope of the view can't be altered/reduced), we'll be able to see the total number of Story Points, but not the rolled-up values.

It'd be great if we could (for instance), show the rolled-up values next to the total value inside of a parenthesis. Having a way to distinguish how many points were rolled up from a specific work item type would also add value to the Timeline.

This would allow for a quick overview of the given values while looking at a collapsed timeline.
