A little problem regarding ice spawn, especially on maps like water world.
Ice are spawned even with lowest ice ratio settings, which may not be something good to see in tropical themed maps.
Hence I'd suggest a No Ice setting for the game editor, which disables ice-water ratio and all waters will be water without ice in certain worlds.
You can help by EXPANDING IT.
I also this can be done with no ice button, you could just expand the arguments that can be inputted into the terrain parameters, and allow the lowest slider input to not generate ANY ice
