That's OH MY GLITCH!
Previewing and Decorating Walls, Floors, and Ceilings is Way, way, way, Too, too, Sloooowww!
Speaking of Walls, Floors, and Ceilings; would be nice to have some matching stuff, say for things like Metal Floors - No Metal Walls or Ceilings.
Would be nice to have some appropriate Walls, Floors, and Ceilings for things like Produce (Broccoli Trees just don't do it for me), Spice, Metal (a Pollokoo, Collopee, or even Deeps backgrounds with matching ceiling and floors), Herbs and such. Things like Corn Fields or even Garden Plots maybe like Kipacre Greens and such.
This is, of course, my opinion, and while I'm only one voice that's my opinion.
