I'd like a cuboid mod that has at least the protection feature in it. If there isn't one already I'll make one myself I guess... I really want to just be able to click two corners like the old cuboid.
What i don't like about worldEdit is the fact that you have to use a command to select the blocks, or the stupid wand thingy... In cuboid you can you a shovel, or what ever you choose.....
WorldEdit + WorldGuard. I was anxious at first too, but the differences aren't that many. There is only one feature I truly miss; CuboidPlugin had a sanctuary flag, (no mob spawning) but this is (IIRC) actually not even technically possible with Bukkit at the moment. I think, and hope, it will come once it is possible though.
