I cant seem to find a way to spawn tipped arrows into kits with /i I cant just add on effects like potions from the meta http://wiki.mc-ess.net/wiki/Item_Meta

Please can you add it so we can spawn tipped arrows from a command that can be used in kits. Look at the potion meta page, should be the same as that.

They can be spawned now using the new Item DB implementation.

For example:
/i tipped_arrow
/i poisonarrow
