This plugin lets you take all of the loose ores you have in your inventory and make them into their respective blocks. I might see this useful in prison servers where you can fill your inventory very fast with ores.
All you have to do is /block and the plugin finds all the ores in your inventory and clumps them together into their respective blocks. As an added bonus, the plugin also detects remainders (because a stack of 64 ores is 7 blocks with 1 ore remainder).
I may add permissions later if anyone wants it.
As always, more later?
