Create a 'Kill Currently Running Tests and Execute Selected Tests Immediately' button
The existing 'Run selected test(s) in new process' button just gives the selected tests high priority. This is very irritating when longer running tests are clogging the queue. I often go to the Processing Queue to kill the tests I don't care about so that my test will start sooner. Worse, sometimes the test I want runs together with long tests I don't want, so I can't kill just the long tests without removing my requested test as well. Just run my test, right now! The others can wait.
