FastOre

Vein mining for every ore. Break one block and the whole vein follows, connected ore by connected ore. Every block still costs a point of pickaxe durability, so a big vein costs a big chunk of your tool - no free diamonds. Drops, experience, Fortune and Silk Touch all behave exactly like vanilla, modded ores are detected automatically, and the O key opens a menu to toggle ores per player. Note that many servers treat vein mining as cheating - check the rules before using it on a server you do not own. "o" open settings.
