I'm having a hard time figuring out of the custom section allows the mouse image to switch between an 'idle' as well as a left and right click image. If this isn't possible, would be a very nice addition.
Also, would be really nice to have an option to completely disable drawing of the arm. This way it gives people ability to use the mouse image as a free floating thing, and swap between mouse inputs like above. Kind of like how Rayman has hands, but no arms.
