Movement indicator
This is separate from my WASD movement suggestion from before, because it would be only useful with the mouse cursor...
When you click on a mouse, could the square that you just clicked somehow "flash" or "glow" or something so that you could tell where your destination is? This would be really helpful when you're doing chip races, and when you're clicking on NPCs or other players, or tables, or slot machines, or .... :^)

We actually wrote this functionality in locally, but at least for now have decided against using it as it just doesn’t “feel” right for immersion. We may revisit this again at a later date.
