Hi,
If I understood what you want correctly, this is already available.
In a plugin with the CMapEditorPlugin context, you can use Cursor.Brightness = 0.; to totally remove the cursor's visibility, or put it at a low value to simply reduce it. You may also change the color with Cursor.SetCustomRGB(Vec3);
Also,
anyway there is no really a reason to show a player if the block cant be set, if he sets ghost or blockmixing on
There are some situations in which you cannot place a ghost block, for example if the block is already there.
