So simple addition that I'd love to see is simply to use the kit feature and add some block-kits. Example; /Kit Stone - Stone brick, stair, slabs, andesite, smooth stone, cobblestone wall, cobblestone block, stair slab. /kit spruce - all spruce items /kit quartz - all quartz items (- netherrack one maybe) You get the gist. Hope this can be implemented, easy to add and it's a very useful feature.
/kit {Color Palettes} /kit {Best Approximate Color Scheme Palette|Baroque|SteamPunk|DieselPunk|CyberPunk|Tron|ComplimentaryBlues|SplitComplimentBlues } /kit {Water Effects} /kit {IceNSnow|Sand|Nether|etc} Idk I'm out of suggestions at the moment.
