Directional spread

I THINK it might be worth a look to see how a direction path can be made to lay a line of blocks down as 1 input , Lets say place 1 oak block on a flat land . You have a side option to enable, this will allow you select a number between 1 to 9 , a simple direction arrow dictate the direction of placement, N X 9 OR S X 9 , while enable you will place 9 blocks in the direction of choice with every 1 action . If the user decides to break a block from the 9 laid , let's say number 6 then the remaining blocks stay in the place they were assigned and the 6th block is destroyed only .
