Well, I meant all the shaping morphs should be injectable. L & R morphs could be under their own list for organizational and cleaner navigation purposes. 

So, an example would be:

CheekbonesHigh
CheekboneHigh_L
CheekboneHigh_R

That way the character artist could set the L cheak at .45 and the R cheak at .48, or whatever. 

and,

CheekboneHigh_L
CheekboneHigh_R

could both be under an 'Asymmetry' header, and even be their own set of injectables. There's no limit to how many menus and sub menus there can be in the parameters pallet, but some forethought on organizing is important.
