One of many applications: Now we can have a full crafting system.
With TableData/Items/StructureDeconstruct.xml, we can gather the ressources from the environment.
With transforms and merges, we can shape/refine them into different materials.
With TableData/Items/StructureConstruct.xml, we can make some of the items placeble on the terrain.

EDIT: It could be interesting that the deconstructed tile be replaced by something (or nothing, as it is now), defined by xml (StructureDeconstruct.xml).
For example, a deconstructed tree with an axe becomes a log, or a mined rock with a pick stays a rock (the same or a smaller/different one, without the "ore"?)
