With the popularity of using multiple pieces of furniture to create "new" furniture and all the crazy possibilities we have through the use of clipping, I feel like we should also have a tool allowing us to link selected pieces of furniture together to move as one object.

Similar to how many 3D design and CAD programs work, a "drag select" tool or simply holding ctrl+clicking to select multiple pieces would be fantastic.

Beyond that, maybe add a function that allows us to group those pieces of furniture into families that can be saved and moved around together as one object.

This would definitely make the task of redecorating much less daunting for most people who are highly invested in their housing, particularly. It would add a huge amount of functionality to a system that can be frustrating to work with at times, also.
