This is purely my opinion and may not be the best suggestion, but it would really help if I knew just how much deviation from the straight shot a particular club had. Another golf game I own and play (GL Golf) uses a narrow white wedge to show the left to right range a shot can deviate in. It gets wider if you're in the rough and narrower on the fairway.
Not saying the deviation would necessarily need to vary depending on lie for WGT, but at least knowing just how much a shot could be off straight would help a little. Obviously more precise clubs would have a narrower aim wedge and less precise would have a wider aim wedge.
And as always, mishits would affect the wedge as well, with more forgiving clubs decreasing the amount outside that aim wedge a mishit shot would deviate.
Again, just a suggestion that doesn't necessarily need to be implemented. I just feel that without the option to test clubs, it's hard to look at the little precision scale and get an accurate feel for how far from center a particular club may hit.
