That is a nice add.
Now tree leaves and Books page can be done efficiently without the need for Solidify modifier.

There are a couple issues:

The backside seems to be extra glossy. I have tried the same settings for each, and the backside is different.

When mirroring a twig the faces are also switching.

The glossy material has a weird legacy behaviour, see https://github.com/LuxCoreRender/LuxCore/issues/301
