Didic thank you for another grate review. I always study them with attention.
I'm trying to follow your suggestions and improve. But no doubt this is a long run :).

On the content issue, as you well noticed I have to say this.

In Blender 2.79 there is the option Filmic. No need to manually add the external folder. And it is much better than rendering in standard Blender.

But this is different from the options when manually adding the package. The name there is Filmic Log Encoding Base. And the difference is not just in the name but also in rendering. Now it remain for the user to test and choose witch is best for him. Hope that this comment clarify the things for someone who want to try it.

Thanks
