- Adding a relaunch feature to the performance tester: you can use the relaunch if you want to measure multiple runs of your app keeping the same metrics alive. New arguments must be supplied - and the step counter will not be reset (this makes it easy to avoid endless loops)
- Having the Sketch test case relaunch itself
