Truthfully the program they have looks fantastic at empowering UI/UX designers to do more with games.
I'm not sure if everyone is aware, but the normal flow is that a UI/UX designer will spend days in Figma; give the output to a programmer and the programmer will (often) say that it's impossible to implement for X,Y reason.
What follows is a back and forth between the programmer and the designer until eventually a design exists that can be implemented.
This is compounded by the fact that there's no good UI framework in Unreal engine, at least not for AAA games.
So, while I have not done a feasibility test yet, the workflow of this tool is definitely the best I've seen and seems to integrate seamlessly with Unreal Engine and blueprints.
I'm personally really excited, because with this it's possible for a UI/UX designer to work without the aid of a programmer.
(also, game programmers tend to hate doing UI).
