 ### Added
 
+- **Multiply tool.** Alongside Duplicate, a new **Multiply** tool asks how many
+  copies you want (1–50) and drops them in a tidy grid — each an independent
+  copy of the part you clicked (same size, colour, material and settings). Great
+  for crates, dominoes and brick walls.
+- **Drop-in vehicles.** A new **VEHICLES** palette section adds a **Car** you
+  place like any other object: a chassis on two sprung, motorised wheels that
+  drives off when you press Run. Its three parts share a group tag, so dragging
+  any one of them moves the whole car as a unit (and the grouping survives
+  save/load/reset). The "Motor Cart" recipe now builds this same improved
+  vehicle.
+- **Scrolling tool palette.** The left palette is now a single vertically

+  · JOINTS) fits a normal-height window — the panel scrolls instead of the
+  window growing. The stack is back to its original 760 px height.
+- **Ramp facing.** Ramps now have a **Facing** setting (high on the left or
+  right) so you can build slopes in both horizontal directions; it mirrors the
+  outline and saves/loads with the piece.

+- **Slicker tool palette.** Section headers are brighter and sit over a hairline
