nanoloot creates a tiny window that keeps track of who looted what in dungeons and raids.
Additionally, nanoloot also provides an option to whisper people to ask if they need the item they looted. Note: If you click the whisper button for loot that you have received, it will instead send an offer message to the group.
nanoloot allows you to customise the title bar colour, and set whether the UI should be hidden when the list of loot is empty.
