In [another thread](https://discourse.nodered.org/t/converting-string-into-json-object/72002), @zenofmud posted a change node with 9 rules.

```auto

        "id": "006ee02eff444905",

                "tot": "str"
            },

                "tot": "str"
            },
            {
                "t": "change",
                "p": "payload",
                "pt": "msg",
                "from": "type=",
                "fromt": "str",
                "to": "\"type\":",
                "tot": "str"
            },
            {
                "t": "change",
                "p": "payload",
                "pt": "msg",
                "from": "error=",
                "fromt": "str",
                "to": "\"error\":",
                "tot": "str"
            },
            {
                "t": "change",
                "p": "payload",
                "pt": "msg",
                "from": "None),",
                "fromt": "str",
                "to": "\"None\"},",
                "tot": "str"
            },
            {
                "t": "change",
                "p": "payload",
                "pt": "msg",
                "from": "None)]",
                "fromt": "str",
                "to": "\"None\"}]",
                "tot": "str"
            }
        ],
        "action": "",
        "property": "",
        "from": "",
        "to": "",
        "reg": false,
        "x": 360,
        "y": 520,
        "wires": [
            [
                "0fdea342bae15836"
            ]
        ]
    }
]

```

Not unnaturally, the OP's response was "I'll have to try and work out why each rule is there"

So I suggest an option to add a comment to each rule in the change node for documenting each step.  
To avoid using up more of the already crowded real estate, could comments "hide" behind a dropdown button like this?
