Runtime gizmos system to recommend?

[niuage]

Since this topic is not directly related to Curvy Spline support, feel free to delete.

Since Curvy Spline has a great API that can be used at runtime, then comes the question: how do I let players interact with it? So I was wondering if you, Aka, or anyone else, had a gizmos system to recommend that would play well with Curvy Spline.

Thanks.
