One thing I would really like to see in the first release is the ability to pick up materials from one entity and apply to others. This is critical when you edit materials (eg colours).

Again I prefer the right click approach.

Right click on an entity and you are offered a menu select:

Copy material - to make that material the active material
Save material - to save that material to the material library

You can then apply the material as normal depending on the entity chosen (eg face/body/part/appearance).
