Currently, there is no way to see what jobs (test runs) have been started or are in the queue to run. Furthermore, there is no way to cancel a job once it has started. Also, only entire test sets can be sent to the job queue, when there are many times when it would be beneficial to submit only a subset of tests in the test set. For example, when you want to re-run a failed test, there is currently no way to do that without executing the entire test set again.
