My wish would be on the animation layers screen the ability to add just the items I want to that layer, instead of having every item present.  This way if I have four figures in a scene then I could make a layer for each figure (or part of a figure like the hands) and not worry if I make a change to a light position or camera angle that it will be placed on the current layer and not on the layer for that item.  It can take some time to go through all the layers to find a out of place key frame.  Also a lock to prevent a layer from being changed.

 

As for the material room you might want to ask for some (a lot) of presets, however I would not want a system to try and second guess what I want it to do.  Having a system that prevents you from making dumb mistakes is also a system that will not let you be creative.  for instance if the shader is going to be applied to the skin a smart shader would say skin can be Tanish/Blackish/Yellowish but not Blueish/Greenish.  Which would be great if you were doing a human but not so great if you were doing the Wicked Witch of the West (who is green).
