Help me with this problem: The model needs to have a more cohesive feedback that the user can provide, but it must be in the dataset format of: prompt, completion, and label. The label is only binary of true and false and the format is unable to change. But you are free to do anything to help make the model's feedback more useful for training. Feel free to add more UI elements, e.g. when downvoting or upvoting, to do this. Also have a slider and comment box about the output that the user can use only when either of the voting buttons are pressed, make it open a ui popup for that.
