I'd like to sat that 1.9 is just amazing. New decoration blocks (endrods/paths/glass rods), new command blocks to make stuff in vanilla more easily, shields, lingering "gas" potions, tipped arrows, and scoreboard tags. And they fixed boats .
What is the deal regarding posting default edits? I've seen quite a few ~0-.5 effort recolor packs, so yeah . I have a pack where I actually do things myself, like nametags becoming red "Hello, insert name here" stickers, and horse armor icons becoming horseshoes.
disableBlockGeneration would be better as a worldgen option, choosing which blocks are generated by the algorithms, like sand generation could instead be watermelon blocks, and you would have deserts and beaches be replaced by juicy, squishy watermelon masses .
