Hi David,

Thank you for your feedback!

The new Code Coverage tool in PDK 7 is actually based on the
Devel::Cover module. It provides enhanced visualization for users, and
also provides management functionality for coverage data sets.  The
latter is not simply for convenience - it also allows for side-by-side
comparison of your code as it changes over time by changes to either
your modules or your test suite (for hotspot analysis and for code
coverage variation).

Some of this is presented in the sample data included with the Code
Coverage tool.  For coverage you can see the improvements of the test
suite in the Data-Dump sample code.  For hotspots the Ana-Find example
set shows the overall decreasing runtime over changes in the code.

We tried to provide users with a better visual overview of their code
based on the details Devel::Cover provides (without having to jump
through 100s of HTML pages). We were hoping to receive some feedback
from the beta users if they actually do find this representation more
useful, or if there are areas that could use additional GUI support.

To sum up, we believe the provided value is in the user interface that
provides the user with a better interface and subsequently better
understanding of their code, over time and/or at any point in time.
We have not as yet been able to finish a tutorial for the Code
Coverage tool, and we understand that makes it harder to grasp the
features provided.

We would be very interested in hearing more about why you find the
Code Coverage tool lacking in comparison to Devel::Cover.

Cheers,
-Jan
