I'm current improving my Test Coverage and collecting some expirience with NCrunch. So I have following Imporvment Ideas for the Coverage Indicator:

The Coverage Indicator which display if a line is coverd or not has 3 States (Green, Red, Black).
I Think there is a 4. state neccesary (Half Green, Half Red).

If you have lines which are covered from different Tests and one of 10 Tests are broken, than is the indicator Red. Looks like that all Test which covering this line are broken. So I would prefer a state which indicate that only a couple of tests are broken (e.g. Half Green, Half Red).

A other Improvment are for the ToolTip of the Converage Indicator.
If you click on a Indicator, you got a list of tests which covering this line. If you have broken tests, it would be helpful if you can se there the Error-Output of the broken test. In the moment I search for the test in the "NCrunch Tests" Window and display there the Error-Output.
I would prefer to see this Error-Output in the Line Converage indicator, too.

Best Regards
