I've been editing world maps for a while now using the plethora of tools available here, but there's one thing I still haven't figured out how to do. For example, in Un'goro Crater, this light is less than desirable. It's all green and I'd love to change it. In the SharpWoW map editor there is a tool that allows you to graphically change the color of the different lightlayers, but refuses to save, saying that the relevant file is already open. Are there any other tools that permit changing the colors of the light?
