### About Editing nodes
When editing a node value, the JSON value type is determined based on the value.
For example, after inputed `10.5` and saving the JSON to a file, it will be output as a float type `10.5`.
If the value sorround with `"`, it will be output as string type always.
The following is a list of conversion rules.

| input value        | json type |
|--------------------|-----------|
| `gorilla`          | string    |
| `10.5`             | float     |
| `5`                | int       |
| `true` or `false`  | boolean   |
| `null`             | null      |
| `"10"` or `"true"` | string    |
