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

About adding new node

For expample, you have following tree.

{array} <- your cursor in there
