The following features are missing
Reset map original location
Fade out duration and effect for level unloading.
Change streaming range, until unload. Currently it seems, when you want to change streaming range, you have to remove maps from layer, remake the layer?
Resize streaming layer margins. Not entirely sure about this, but WC shows a set margin, not sure why it has to be the size it looks per default.
Threshold for unloading based on player fps.
