Lately, redstone creations has been made more and more compact. But still, some aren't compact enough to be able to use it small builds without have to expand it. So, if Mojang could add a Customable Redstone Output block/item. So then logic gates and redstone clocks would be make much easier as well as it's extremely compact. This might not be release soon (or may not even being implemented), but still, that would be great for redstone builders like myself.
As a redstoner myself, this is an interesting idea, but it seems kind of overpowered, to say the least. You could just pop a clock circuit into one block next to a piston and then your done. This would be nice, but it might take away some of the fun from redstone. Partial Support.
