It'd be nice to have the different sand types on different biomes.
I'm not keen on the sand on the Tropical Biome, it seems too Sand Dune/ wavy beach looking? So having the sand from the Mediterranean and Desert Biomes would be a nice replacement.
I also love the stone looking dirt used on the Alpine/Taiga Biome, so that'd be nice to transfer onto other maps.
I for one would love Shale from JWE to make a comeback!
Maybe we could also have a short/tall grass tool added as well for the Foliage tool?
