Something I would like to see in a future update for JWE2 is for all the different foliage and terrain paintbrushes added to all biomes in sandbox mode, which it makes a lot of sense and would allow players to be even more creative with their enclosure designs, which we already have all rocks from the different biomes added (I know that's not a fair comparison as the rocks are singular, placeable items but still). Like what if someone wanted to make a park with different biome types for different species. For sandbox, you could choose if you want all biome types or stick with the biome that's for that map, just like the mixed eras option. The menu would be similar to the decorations and would separate the foliage and terrain by biome (Tropical, Desert, Alpine, Mediterranean, etc.). This is something that I think would add another way to make sandbox an even more great experience.
