Show test result in task if any test result is recorded.
Extend description with more build results
It would also be nice to be able to hover over the task to get a more descriptive text. See proposed hover text in the attached screenshot.
I also think this would be a really nice feature, though perhaps not exactly like in the screenshots - I really like the current flat background status colors.
