There should be an improvement the /fill command with sub features such as /fill sphere, /fill circle, /fill cube, etc then add the size radius then the type of block e.g. /fill sphere 10 dirt, so this would mean that from the edge of the dirt sphere to the centre is 10 blocks and the actual size of the dirt sphere is 20. and the new command /brush is similar to world edit but it just smooths out blocks in an area specified e.g. /brush 10 smooths out an area from the player in a radius of 10 blocks.
