What about extract to parameter? Seems totally missing

```
function greet() {
        console.log(111)
}

greet() 
```

Placing mouse on 111 and extract to parameter should lead to: 

```
function greet(param) {
        console.log(param)
}

greet(111) 
```

But this obvious case is missing and this doesn't bound good for the future as this was the first thing I tested support for. 

Are only simple refactorings possible?
