More compact storage blocks

There are 3 blocks that seem like they could use storage and they all could have a secondary effect Charcoal block - crafted from 9 charcoal would be about the same as coal but would do just a few items less and the color of the block would be more brownish Gunpowder block - since Gunpowder is used now for flying alot of people made Gunpowder farms and it would be alot easier to compact it to make more space so that we don't constantly have backed up Gunpowder it could be a super tnt or just decoration being easily flammable the block would be a deep grey but look almost like a Redstone block since they are both a dust Block of flint - flint only has 2 uses flint and steel and arrows but if we collect alot of gravel for concrete we are going to get a lot of flint and we could just compact it to take less place it would be a smooth blackish color and easily flammable and fire would spread faster on it than wood
