This feature request has to do with the small block wireframe that shows up when you look at a bit in world with a chisel or bit in hand.

Is it possible to make the bit highlighter in world change its color to contrast the bit your looking at so if your working with dark colors such as black you can see the bit highlighter easier. If having it change dynamically would be to much work then how about adding an option to change the highlighter in a menu somewhere.

I think that this makes sense, though I'm not entirely sure of the best option at the moment.

Another way would be to have the bit highlighter change colors between black and white either by fading or a delayed blink.

What if you make it like the cursor, inverted colour? It would show up on any surface then... not sure it would look the best but it's an idea
