that wont happen filler is FAR from useless in the time it saves me clearing out an area i could have gone mineing and got x2 the ores then the filler destroyed if you want the ores just mine it by handThe change to the filler makes it basically useless for carving out caves since far too much goods are goint to waste the way its set up now, i suggest it gets 2 modes, 1 for deleting blocks as it does now and 1 for working as it did earlier, which makes it useful for carving large caves (not all of us love huge holes in the ground =)
