Since changes can obviously made to the original code there should be more uses for some of the items in this game. For example:

Silk is only used for one quest yet there is a silk stall and merchants. Suggested use crafting

2 silks + needle and thread + level 5 crafting = skirt
2 blue + silks needle and thread + level 7 crafting = wizard hat
3 blue + silks needle and thread + 10 crafting = wizard robes

Cabbage has few uses yet it is all over rscrevolution. suggest use cooking

bowl + cabbage + potato + range + 20 cooking = cabbage stew (if spiced vegetarian curry)

I know most of these would go unused but I think it would add more depth to the game.
