1. Shulkerboxes or storage blocks dont get added value. For example: a shulker box is $50, if you add items with a bunch of value inside the shulker box, the shulker box is still worth $50. This is an oversight in the plugin.

2. Having a full inventory doesnt let you pick up new items. Since the "Worth" item lore that gets added to items you pick up doesnt register as being the same as an item that doesnt have that lore, you wont be able to pick up those new items when you have a full inventory. You need to make sure that this item lore is universal, or that an item with the item lore "WORTH" is the same as the actual item.

3. Worth is only shown for items that are picked up by players. Any items that are naturally occuring or never existed in a players inventory all have no worth by default.

On the outside it is very good, but in survival mode when you try to pick up an item that you already have in your inventory (and your inventory is full), you cant pick it up because the item in your inventory has a lore and the one you just got doesnt have a lore yet. This makes it annoying when you have a full inventory because you cant pick up natural items, like when you mine. This plugin would be almost flawless if you did so.
