It would be nice to see in the main job page the list of unit tests which have
changed their state since the last build, instead of having to click through the
latest test results link. Again, I know it's just a click and page refresh but
this is a very common traffic pattern. Unit tests are probably the key artifact
in most builds.

I think showing just the tests which have changed would be informative. You
could argue that showing only the failures makes more sense, or possibly show
both. I guess it depends on how stable your tests are. My vote would be to
show both.

This should appear below the permalinks.
