It would be really, really nice to have a catalogue of materials and the bonuses (to gear score etc) for each. The entries could be locked until discovered, or maybe just titles/names with no stats until discovered.
Specifically, I'd love to see something in the Guidebook so I could look up each material, what its base stats are, and understand what the end gear score will be before I start crafting an item. Right now we have to rely on player-made spreadsheets, which isn't very user-friendly.
In addition, having a list of available materials makes it exciting and rewarding to discover them all.
