Anti/obsidian/dark torches

You guys should add torches with negative light levels. Eg: if it had a light level of negative 8 at source block, then if you placed it next to a light level 8 block it would completely restrict the light from that side. Uses: I’ve found throughout my Minecraft experience that doors let light through, and this makes sense until you get to spruce doors, they have no windows, I thought this ment they would not let light through but they do these torches would solve that. Want a spooky castle with always dark windows, you could do that. The possibilities are endless and it seems easy enough to add. I know you guys don’t have time for all of these, but I hope you consider my suggestion. -Ruby Tellmont Ps can you add a light topic in your suggestions Dropbox
