QuickSmelt

When you mine iron ores or gold ores with the right tools the plugin will drop the corresponding ingot and experience orbs. When killing mobs that drop raw meat, my plugin will drop the relevant cooked meat and the extra experience orbs that you would get when cooking meat (Works perfectly with looting enchantments).

I read the Minecraft Wikipedia, and it seems that when smelting ores there's a bit of luck involved in regards to exp.
Iron ores have a 70% chance of giving the player extra experience, while gold ores give the player a fixed amount. When cooking meat, the chance of getting extra exp is 35%.
I might have misunderstood the wiki, and I could be wrong in regards to the extra exp mechanics. Please tell me if the mechanics are different.
I replicated this behaviour in my plugin so that you don't lose exp.

1.3 Plugin Update:
This update adds the command /quicksmelt add/remove player.
Every time the server restarts, unfortunately, the player list is emptied as it is stored in memory and not on a file (going to work on a solution very soon).
You have a config file which stores two global variables that decided if everybody gets to use the quicksmelt for just the ore, mobs or neither of them. Then you actually have to add each player in-game using the command /quicksmelt to the temporary list to allow them to make use of the plugin's functionalities.
If you don't like this feature I suggest that you use the 1.2 version of this plugin which only has the config file option.
In addition to the temporary list caveat, sometimes the JVM might decide to garbage collect the list that stores the players UUID, therefore, you might have to re-add them from time to time (this might not happen if your server has a lot of ram dedicated). That's why I'm working on a solution to save the player list on a file permanently.
