Cool.

I tried getting some MAT zones merged (notably the lips:skinhead, and making some masks for shader combinations), but the reaction from all texturers was 'WTF!' so that's likely not going to happen yet, people are too used to the separate zones.

The base shaders can always use some improvement, none of us are shader gurus. If the community develops some better shaders and they are OK with it we can either merge them into an upcoming update as a new shader folder, or even replace one of the base shaders. Some of the new morphs and things like the corneas will probably make it in, if only into a 'Bonus Content' folder.

Just keep in mind that user-friendliness is also a big consideration. For example the refracted eyes are significantly better than the default shaders, and I use them in most of my renders, however they load in as beady white 'Marilyn Manson eyes' and if someone doesn't have the proper render settings enabled then they will render like shiny black demon eyes. So they don't really work as the 'default'.
