+1
just yesterday i built a large storage (some kind of warehouse, 20x20 tiles), and thought how nice it would be to put one magic lamp above it and let it display 20 lines of items right in the middle of that 20x20 area :-)
it might be difficult to make this variable with the current method of specifying which items to display, but any new version to display more than only 4 items with a single lamp would be really nice.
