Once Ampps starts and you minimize the panel there is no way to access any Ampps functionality including exiting Ampps. While I hope it is bug that is being worked on, I am wondering what the command is to exit using the Terminal.
I can kill Ampps but rebooting but if I need to restart after a config change thats seems excessive. I doubt I will need it much after the initial setup but thought it could come in handy at some point.
