Small point, but when you go to update a firewall config, it says:
Warning: The changes you made to the firewall configuration have not yet been applied to the server. To do it 'Apply configuration'.
The option/buttun is then marked 'Apply Changes', not 'Apply configuration'.
Also, maybe instead of "To do it"...
