I absolutely adore this mod, the stylization is impeccable. I would love to see it grow to become all-encompassing for my furnishing needs. Here are a few ideas I had while playing:

• beds better detailed than vanilla and connecting
• shallow shelves (perhaps half a block in depth)
• item hook (storage for weapons/tools on display, thinking of Vanilla Tweaks armor stand datapack tool racks)
• kitchen cabinets (thinking of The Sims 4 in terms of shapes and scale between upper/lower) with various stone countertop options
• variations for drawers/cabinet doors (Perhaps 3D drawers+knobs?)
• sink able to be made into infinite water source would be great
• ice box food storage, 1x1x2, double chest storage size
• oven functional as smoker
• cushions for chairs/benches (could also be implemented as a throw pillow for armchairs/couches with would provide additional customization for those pieces)
• table cloths for tables (could also be implemented as a throw blanket for armchairs/couches which would provide additional customization to those pieces)
• shower (could be implemented as knob item and showerhead item as a glass wall could act as enclosure)
• bathtub (could be implemented as faucet and knob item as stairs can be shaped into a tub already)
• toilet
• blinds (Macaw's Windows has a lovely implementation of these)
• side tables smaller than a full block
• coffee tables shorter than a full block

I believe that all of these concepts in action would allow one to furnish an entire home with ease and function at a believable and immersive scale.

Thank you for taking the time to read, have a good day and keep up the amazing work!
