ItemUtils
All this plugin does is adding some details to the items on ground.
With this plugin, every item on the ground gets a display name that shows their name and count. Rare items will spread sparks and all items will blink red right before they despawn. Hologram items (items that never disappear and usually can't be picked up) won't get affected from this.
You can see the gallery for some examples of items on the ground. Have fun! (and a nice day)
