 ### 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
-- 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)
 
 Any Ideas feel free to make a suggestion [here](https://github.com/DriHut/ReFramed/issues).
