That's fine, but how about the selectable options?

In the public version of the plug-in, the selectable dark level option has been removed in favor of code integration. This allows to have a simple and practical interface.
By default, the dark level 2 is chosen but it is possible to have the dark level 0 (at night hours) by selecting diffusedBounces = 0.

If you still want the selectable dark level option, I can make this beta test version of the plug-in resizable.
