Change the term "Room" throughout the software

The term "Room" only works for a small subset of shops. If you're making furniture, store fixtures, etc. this falls apart - you can't put a "Room" into an actual room. Yes you can change it in the options but it doesn't change everywhere and is confusing in conversation. I'd suggest a hierarchy something similar to this:

Job or Project Number - top level
Item Number (or "thing" term) - A project has a list of items that is being built - may be a mix of rooms full of cabinets, assemblies that go in multiple rooms, etc. The term "Item Number" is currently used as the product (assembly) ID in the Products table of the database and labels each cabinet (product).
Product Number - What is now "Item Number" would be better if it were "Product Number". The library is filled with "Products" yet they are currently given an "Item Number
Room Number - The (actual) room or rooms the item goes in.

There is a current discussion about this but I don't think Sarah posted it as an idea so it could be voted on so this is somewhat of a repost. The image may help to drive the point home. I can't even imagine the logic that went into the current terminology.
