Right now you can rotate and move furniture but some furniture isn't symmetrical so no matter how much you rotate it your space looks uneven. The pieces of furniture that annoy me the most are the L-shaped couches. You can't evenly line up these L-shaped couches to be symmetrical, but if there was a 'Mirror' check box to flip it when placing it similar to the option to lock something onto a grid you could line them up properly.
