I was just admiring how beautifully certain blocks blend into each other (broken stone and dirt or different sand colours for example) and thought that a tool that “smoothes” out the cracks between stone blocks/chunks, Gleam, Sandstone etc. in the same way would be quite useful. It could be used just like the chisel in regards of being used on the edges of a block to turn this:
yepp, that would be reeeeeeeeeaaaaal cool. I sometimes think of buildings where I want stones to blend with sand or dirt, but on others it would be not so nice … so THIS is a solution ^^
