If we can toggle the blocks, we can't place them on eachother..
For once i agree with Mattpoppybros. This wouldn't only ruin Redstone, But Building in general. Why get an iron door if it is made useless? the whole point of Iron doors, Pistons, RedstoneLamps,And Redstone in general is that is activated by REDSTONE. Here are some other options. Carry a stack of gravel to build a pillar in the nether. If you want a door that you can just click, Make a WOODEN Door. That Easy.
