Pretty self explanatory. Give us the ability to put a half or quarter slab (either or, we probably don't need both) in the middle of a voxel grid. This would allow us to create more symmetrical rooms in smaller areas, give us greater control over our aesthetics and generally be a quality of life addition for building in general.
Obviously this isn't an important addition, but my guess is it would be rather simple to implement.
