Google translator is good.
The thickness of a pane can be reduced but not smaller than 0.001. This is really thin.
Problem is you cannot scale a pane for other building possibilities, so you have to edit it manually, every time.

RE: a few more VERY useful block shapes
Actually we did already prepare some of these block shapes
This is a rough overview of the upcoming block shapes:
half sphere
hollow half sphere
quarter sphere
hollow quarter sphere
eighth sphere
hollow eighth sphere
alt. slope corner (slope corner type that was still missing)
Probably we'll add them shortly after the npc update. We'll also increase the quality of the cylinders, hollow cylinders and the sphere (so they appear more rounded).
We'll think about the inverted cylinder and the hollow cone / hollow half cone. What would be the use-case for these shapes?
