The Hairline Issue, Could A Slider Fix This?

In my opinion, hairlines have always been a swing-and-a-miss in TS4.  Some hairs sit beautifully, some far too high, some too low. 

Take the hairstyle that Eliza Pancakes wears for example. It sits SO high that it makes Sims foreheads looks massive.  Put a different hair on the Sim and suddenly this area of the face looks much smaller. 

This issue of hairs sitting too far back or too high up plagues so many hairstyles across many packs. Take the hair from the Paranormal pack, for instance.  It doesn't sit well at all. 

I think a really good fix for this would be to introduce a hair slider that isn't locked to CAS.  It would enable us to move hairs up/down, forward/back, to make sure that hairstyles sit consistently on a Sim no matter which style we are using.  It will also allow for more unique Sims as small/large foreheads wouldn't be cancelled out by styles with closer or further back hairlines.
