At the moment, when one of my jobs in a nested view has been aborted, the icon of the nested view is gray ("Aborted"), no matter how many yellow or red builds I have in there.
IMHO, green/yellow/red is much more important than the "aborted" status (even if you could distinguish it from the equally gray "disabled" status, but that's another problem)
The summary status should have the following priorities (low to high):
- disabled (grey)
- aborted (gray)
- success (green)
- test failures (yellow)
- error (red)
So red should always win.
