I don't remember if I already asked for this, but we have a lot of test plans that we run for every major release. By default, when a user creates a new test plan, the name that appears under the test plan when you click on the specific milestone is the author, not the assignee.
It would be nice to have a default assignee for the test plan. It would be this value that would be shown when looking at a specific milestone (to see each test plan progress, etc.).
I know the default assignee could be different from the test runs and that we should assign a specific user for each test run, but at least we would have appropriate reporting at the top level because it often happens the creator is not the one responsible for the test plan afterwards, etc.
