I'm often frustrated that I can't check my virtual machine settings while the VM is running, and in many cases, I would like to change the settings for future use but don't want to shut down and then reboot the VM to continue working. Could you add the ability to view and change settings while the VM is running, and then those settings would take effect the next time I restart the VM? I think this would be a lot more useful than simply being "locked out" of the settings whenever it is running.
