Decorative block to indicate that the block is redstone powered for Java.

What if we had a way to tell if a block was being hard or soft powered when it is being powered? For example it could glow like a redstone torch, maybe just have a red outline? Brighter red for hard and softer for soft?

Perhaps also a decorative slab and/or block that players can use to indicate that redstone is placed on top of it. This way when digging around it would be easily identifiable before the block is broken with a higher contrast colour. I was thinking it could use the texture of the base of the comparator and perhaps take slightly longer to mine than an average block

New users could use it to see where the power is going and experienced user could use it in debugging their machines. It might also make often ugly redstone contraptions look a bit better or more technical.
