Re: How to track test case development?

There isn't a lot of options in this area.  Off the top of my head, I can't remember a way to do this using reports or gadgets.  But you could use the Test Cases homepage and add filters, saving them for each status type so you can monitor numbers - and depending on how your test library is structured (e.g. folders by team, function, etc.) you could then view the status of test cases in each of those folders.
