[FEATURE] Customise the wrapped text

[Jab2870]

Currently:

[
    {
        "name": "Bob",
        "age": "22"
    },
    {
        "name": "Steve",
        "age": "23"
    }
]

shrinks down to

[
+---  4 lines: { ----------------
+---  4 lines: { ----------------
]

It would be nice if we could customise the shrink text so that it instead shrinks to something like:

[
+---  4 lines: Bob ----------------
+---  4 lines: Steve ----------------
