I love the storage options of enhanced Inventories with lockers and sizable chests (and double chests) would use them exclusively if they were compatible with Grief Protection on the server. In my opinion these should completely replace iron chest as the go to chest mod. On a good note, they can be made private for 1 gold ingots, and 6 nuggets. but can;t share them with parties. I also like Storage Drawers with its 1 item, 2 item and 4 item storage, that are upgrade, but not as much as the simplicity of Enhanced Inventories.
Im not sure of this possibility of making them compatible as if it was simple im sure the @Administrator would have already done it.
from what i remember its not that much that needs to be done to Gp things. you just need to add them to the Gp list. but then again my memory is failing me on a regular basis tho:/
