Morph dials can be deleted from within Poser.
You can not yet delete full body morphs.

The cloth Sim runs quite a lot faster now as it uses all your cores if you have a multi core CPU.

I organise as follows. (knowing that any sublolder in Poser can now house anything.)

I make a new figure; I create a folder : "My new figure".

ALL goes in that folder.
The obj
The Cr2
The textures
The mat files, ALL go into the same folder.

When I want to transfer "My new figure" to my second PC, All I have to do is copy that single folder as all is in there.

The morph brush.

I do not know your 3D modeling skills, but see it as a controllable displacement morphing tool.

You work directly on the mesh.
You can create, combine existing, push, pull, soften, to screen or surface.
Quite flexible.
Holding the shft button when working on the mesh will prevent it from switching between meshes if 2 meshes are close together.

Some are very good with the morph brush, some find it difficult.
I would call myself "moderate" but learning.

For your question 6, No not yet.

But you get a dot in front of any dial is not at its "ZERO" position making tracking of what you did a lot easyer.

PLUS????
From Poser6 to Poser9 or PP2012?

IDL worth its weight in GOLD.

LOTS of improvements.

PS, the new Library is completely rebuild also, and uses a new structure also.
I think you will lke it.
