Russian:

If you need to make (all) the furniture unvisible, then click in the furniture list (bottom left window). On the keyboard do CTRL-A , then do a right-click. In the modify window that opens, you can make all furniture invisible.

I agree that layers would be a nice feature, it has been requested several times before. Who knows what the Easter bunny will bring in version 2.4, or else Santa Claus in version 2,5 or 2.6??
