 ### What Shapes are planed to be added
 Currently, the list of shapes to be added is pretty simple as the mod is still under development:
-- Wall
 - Fence
-- Pane
 - Button
 - Pressure Plate
-- Trapdoor
+- Carpet (maybe redundant with Layer)
-- Door
-- Carpet
 - Post
 - Half Slab (maybe redundant with Layer)
 - Slabs Stair (a stair with one end being of a second theme, might be done in multiple blocks)
