Hi all,  
I would like to change a property of the config node during runtime.  
The idea is that the node can be reconfigured during runtime and the values should be persisted.

Let's take the following use-case: I want to turn on the logging flag during runtime using a msg:

```auto
msg.payload.logging = true;

```

This message is received in my node and the logging flag is written to the config node.

```auto
this.on('input', function (msg) {
    node.config.logging = msg.payload.logging;
    // and now???
}

```

So far so good, that works during runtime, but the changes are lost when I restart node-red.

Question:  
How can I make sure that the changed logging flag is persisted?

Any help is welcome!  
/KH
