"Less Dirt" extends the grass growth on the side of blocks so rolling hills show less exposed bare dirt. Also does the same for snow, forest litter, moss, etc. This improves screenshots in a similar fashion to Landscape redo but doesn't alter nodes.
Removes a piece of Minecraft's style legacy that Notch might not have gotten right.
