The same way code coverage can be reported line-by-line when browsing a file in Diffusion, it may be interesting to display information about audit coverage that same way.
Of course, report generation per file, per folder, per project of audit coverage may be interesting too.
With some generic support, Diffusion may be able to handle any annotations associated to folders/files/lines with quality data like code complexity, test coverage, audit covert... So that any extension may feed them the way it want.
