Hi,
I find I'm using these commands more and more in my building, it certainly can speed up the construction of large areas. One Command I would find very useful is a reselect. I'm thinking this could be especially useful for placing say multiple level floors or adding walls to a building where the only change to the previous selection is in one dimension for examplethe height.
Currently I'll select an area then use the place command to place the blocks. Then have to go through selection again for the next floor, it would be great to call back the previous selection and simply raise or lower the height for instance.
there is reselect sort of add -p to the end like /we fill dirt -p
