feature request: adding testsuite to testplans

Hello,
This is a two part request

1. allow users to add testplans without forcing them to select a testsuite. A lot of time, we don't really have the appropriate test suite and we are just in planning phase. Creating a framework by just adding empty testplans is fairly common. Once the team agrees with the skeleton test plans, we then work on adding tests/testsuites to the plan.

2. permission control for adding testplan and suites. Assuming that #1 is implemented, it then becomes important to control who can add/delete testplans vs add/delete testsuites to testplans. Allowing this level of control in the roles would be great.

Thanks

Ali
