Delayed Property Attribute

Delays applying changes to properties while they still being edited in the inspector. Similar to Unity's built-in Delayed attribute, but this attribute can also be applied to properties. 

// Delayed and DelayedProperty attributes are virtually identical...
[Delayed]
[OnValueChanged("OnValueChanged")]
public int DelayedField;

// ... but the DelayedProperty can, as the name suggests, also be applied to properties.
[ShowInInspector, DelayedProperty]
[OnValueChanged("OnValueChanged")]
public string DelayedProperty { get; set; }

private void OnValueChanged()
{
    Debug.Log("Value changed!");
}
