Capacity bars on features and requirements that show when logged work has gone over original estimate

Capacity planning (when enabled at the product level) shows work remaining, work done and work over capacity at the release level in the form of coloured bars (green, blue and red respectively)

It would be very useful if this same graphical treatment was extended to features and requirements so that it instead of logging time/story points until the work estimate reaches 0 and stops, it also shows when more work has been logged than was originally estimated.

A red bar would work nicely for this and give a clearer visual indicator on the feature/requirement that additional work was being performed.
