Getting picky here, my apologies ;)
You might have noticed the indent in front of `zabbix password`, and not in front of `Root password` when you run the wizard. That's because of `desc`. If you do this, it lines up nicer:
```
[{
    "step_title": "Database Configuration",
    "items": [{
        "type": "password",
        "desc": "Enter your MySQL password",
        "subitems": [{
            "key": "wizard_mysql_password_root",
            "desc": "Root password"
        }]
    }, {
        "type": "password",
        "desc": "A 'zabbix' MySQL user and database will be created. Please enter a password for the 'zabbix' user.",
        "subitems": [{
	     "desc": "Enter your Zabbix password.",
            "key": "wizard_mysql_password_zabbix",
            "desc": "Zabbix password"
        }]
    }]
}, {
```
