More sulfur functions

I think adding sulfur to minecraft is a very good idea, however, sulfur as only building blocks disappoints me and looks like a wasted idea, but i suggest adding sulfur crystals, and once mined, they will drop something like "sulfur dust", a resource to craft functional items, like a repulsion potion that makes mobs avoid the player (due to the smell of sulfur), adding strategic gameplay.
Another idea is to add special bombs crafted with sulfur dust that release toxic gases upon explosion, poisoning nearby mobs or players, creating more tactical options in combat and exploration.
