Allow multiple instances
Allow running multiple instances of this run configuration in parallel.
By default, it is disabled, and when you start this configuration while another instance is still running, IntelliJ IDEA suggests stopping the running instance and starting another one. This is helpful when a run configuration consumes a lot of resources and there is no good reason to run multiple instances.
