As in many other topics have been discussed, the colors and opacity of the swing meter can be changed. While it can be helpful, it still is problematic because while some colors work when hitting from bunkers, they might not be perfect when having water in a background etc.
So what I think this game needs is a solid-colored frame for the swing meter that most other three-clickers like Links 2003 has. It wouldn't need to be very thick, just enough to give some contrast. Also giving the user ability to change the color of the frame and the possibility to enable/disable it to suit everybody's taste would be ace.
