Neon’s veinminer

Neon’s Veinminer is a utility mod that makes mining much more convenient. You can press V to turn the veinminer function on and off by default. When active, any ores you hover your crosshair over will light up on your screen, showing you what blocks are going to break before you mine them. The mod also adds a custom enchantment to the game that auto-smelts ores into their refined drops as you vein mine them.
