it would be nice to be able to Craft or Compress redstone into blocks. if you want it to be industrial then 8 redstone dust in a compressor could make 1 Redtstone Block. or you could make it simple in a crafting box so that 9 redstone dust = 1 redstone block that can be easily pulled apart as needed. if you require it to go through a compressor then make it only breakable by placing and breaking it apart for 5-8 Redstone dust or macerate it for a garunteed 8.
these Redstone Blocks should also be able to be placed resulting in a few functions, heres a list!
1: when stepped on causes the block to light up just like Redstone Ore blocks.
2: can accept and redstone current from anyside and send restone signals out in every direction when powered by a restone current, this would work like an instant Repeater that can go in all directions, not just the outlet, the only way to turn if off is remove all On signals (this would basically become a temporary redstone torch since it would stay on at all times.
3: this should be controlable using pistons. this could be used to bridge gaps in redstone wires to active specific signal wires along the same redstone network.
4: would act as a very usefull storage block and would have the same texture as the Redstone Dust in your inventory. mainly red with occassional black dots.
edit: i would greatly appriciate this to be added since IC2 requires so much redstone dust and i'm sick of it taking up several chests in my house.
