Im requesting a plugin that shows you the data value of the item u want for example as a command /dv stick then it will say "Stick - #280" for words with spaces you use _ for the space example /dv Iron_Sword if you do /dv Iron Sword is says "Error item is invalid or change the space to _"
Can I also suggest that the ones with spaces just not have a space in them? /dv IronSword for instance; a lot of current item spawning plugins use this to make it easier. To be honest you could just as easily do no space or underscore - just remove the underscore from the search term so Iron_Sword becomes IronSword. Then it's up to the user which way they prefer to enter it
This plugin already exists from a few authors. SearchIds and I believe WorldEdit has something like this in it.
