Tables

Hide under them, run around them, quickly place model tracks under AND around them.

Tables are a stable of many places. Without them, where would you talk? Easy, by standing up of course. Where would you eat? Easy, just hold food in your hand or get a plate and use utensils. Ok then, how about filling an empty room with something to put stuff on? EASY, just put it on the floor.

Fine, so you don't use tables. Well if you DO happen to use them in Thingamajigs, you'll find them handy for nearly everything. Put your favorite item on a plate on a table, or place a trapdoor next to them and hide under tables, it's quite fun!

Not only that, but tables connect together visually, including copper ones at different states (copper connecting tables with different states only in NeoForge versions of Thingamajigs).

Tables can be stacked on top of one another to make pseudo-shelving. Clever, right?
