HouseOMatic is a work-in-progress Windows app for tinkering with EverQuest 2 Saved Layout files for houses.

Once it's completed, it will load in a layout file, let you select one item to tinker with, strip the file down to just that item, help you find the right one to manipulate by putting items into the crate or pulling them back out again, and letting you adjust the values.

Right now it's in really early preliminary versions.
