I am very bad at making things without patterns, and i was going to randomize a wall with yellow concrete, and concrete powder, you might ask why that is important. You see, i couldnt, blockgravity was dissabled, but i still cant Worldedit concrete powder or gravel.
Its just anoying. Just allow OPs to use all blocks with W/E, pls pls.
Edit : I mean all blocks you can access in regular minecraft, not stuff like end_portal, or moving_piston
