"If a blueprint implements an interface function that returns a value, it is not possible to reference function parameters by right clicking and searching for them. In regular functions, if a function receives a parameter Foo, you can right click anywhere in that function and search for "get Foo" and reference the parameter without drawing a line from the parameter to the place where it is used. It would be highly beneficial if this worked properly for interface functions that return a value."
Expected: You are able to 'Get' the input in the same way that you are able to when searching for inputs in a function.
There's no existing public thread on this issue, so head over toAnswerHub just mention UE-75710 in the post.
