All the Spiral Modular Tables are square. Maybe have round table options too? It would spice things up a bit.
Details (since people think suggestions should be suggested to the finest detail): There would be color variations just as the Modular Table has... Blue, Red, and White. They would be unlocked in the same sequence the other tables are unlocked. The Spiral Red Modular Table gets unlocked and so does the Red Spiral Circular Table. The table would take up one tile, just as the square one does. The design would match as closely to the square ones as possible. I'm not sure what other details I should add. Quite honestly, I'm just suggesting round tables and the devs should come up with the details if they agree to implement this.
