Currently when duplicating a material, everything gets duplicated, EXCEPT Custom Parameters. To add to this, the custom parameters are tucked away at the bottom.
It makes more sense to add the Custom Parameters to the Identity Tab AND copy these values as well.
The sorting of the materials could also use some extra parameters.
Right now you can only sort by name. To keep your browser organised you're forced to add extra coding (Keynote, type, architectural element) at the beginning of the name. Adding a Keynote column to the Browser and allowing us to sort by keynote solves this problem.
