We need a Redstone update for advanced Redstone mechanicians.
These are things that should be edited:
Redstone Repeater: Able to set itself to a custom tick.
Note block: Range of all octaves.
Here are some updates I came up with for Redstone update:
Blackstone dust: A dust that works like Redstone, but is in black color. It does not connect to Redstone but can still be powered through a block.
