Hey tintwotin,
don't know how to rotate and find it hard it bit hard to see, where exaclty the blocks are placed now... don't know maybe there is a better to illustrate the block position... maybe "full blocks" just a bit transparent.
Thanks for the reply. You just drag outside the cube, and it'll rotate in the direction you drag. Are you on a computer or a touch device?
Often you want to look in one direction to select a row, and then rotate to the side to toggle to the right position inside the row.
