Improve array property view

[ze0nni]

Its hard to navigate in a large array property:

How about display user defined data instead class name?

@ccclass('AppViewPrefab')
class AppViewPrefab {
    @property(CCString)
    @displayName // << like this
    readonly id: string = "";
    @property(Prefab)
    readonly prefab!: Prefab;

    // << like this
    toString() { return id; }
}

@property([AppViewPrefab])
private prefabs: AppViewPrefab[] = [];
