This is a suggestion to change/expand the way material disabling works with the mod, in which instead of only being able to provide the material name and all parts are disabled globally for that material, it would allow you to set the material name by itself and or also let you set the material name and then consecutive tool part types afterwards:

material ID -> alone would disable all tools (same as it was originally)
material ID:part_name:part_name:part_name:part_name etc. -> disable specified parts

Example:
miscelleaneous {
# Here you can remove any material by adding its id to this list [default: [paper]]
S:"Remove Materials" <
paper
stone:pick_head:axe_head:pan_head
>

I would go for something like

materialId:part_name,part_name,...

But yeah would be a really neat addition

Awesome!
