It would be really nice to improve the navigation of the JUnit report. What the
best solution is I am not sure, but something more along the framed look so you
can switch between packages and classes without using the back button a lot
would be useful.

Unfortuantely I am not really a front end developer otherwise given some time I
would take a good stab at this myself.

I have not looked at other plugins reports but a common approach the could be
applied across plugins would be really neat.
