Besides that, there will be more of the room visible, without the cluttering of poses covering the view.
There could be a separate icon that is always visible that is dedicated for showing what pose your partner has chosen, otherwise it would be hard to notice when your not looking under that category.
Another way I thought of just now would be buttons for the categories on either the top or the left and when you press one that category expands into buttons for the poses under that category, then the transparent selection thing could be hidden at times and more of the view would be visible.
