As a member of a multi-disciplinary team, I need a breakdown widget that breaks down the work left by components so that I know whether I need a hand or someone else does

This is supported by the "Classic" gadget, but not by the one that was just released in v6.1.6. Since Rapid Boards have the concepts of quick filters and swimlanes, these may be better than just the components.

Please see the screenshot for an example.
