This seems super cool! I wonder if it could be integrated somehow <3 Thanks for sharing :) I hope I will get the time to look into this soon.

So does this mean I can use it in a method of a serialized non-unity class? If so how? I have list of C# objects inside a ScriptableObject. C# objects have a method. When I add the [Button] attribute to that method it doesn't work. Here is what I'm talking about:

public class MySO : ScriptableObject
{
    [Serializable]
    public class MyClass
    {
        [Button]
        public void MyMethod()
        {
            Debug.Log("Doesn't work...");
        }
    }

    [SerializeField] private MyClass[] myArray;
}

I don't see MyMethod button in the inspector...

PS: I love the project! I will include it to my tools package which I use in most of my personal projects :) thanks a lot for this!
