Guess what? The IMVU furniture moving controls allow you to move your items side to side 3 feet off of the furniture node! (use the cntrl button for this feature). This will allow you to place your standing spots almost anywhere. Guess what else? You can *also* use the shift button to move your furniture up and down 3 feet. So if you want your friends to stand on a coffee table, you can place a standing spot there too.
