More Red adds redstone logic gates as flat, plate-shaped blocks that you can rotate and place on walls and ceilings, with a placement preview before you click.
It also brings wires and cables that connect anything to anything and run along walls and ceilings. Works on Forge and NeoForge, Minecraft 1.15.2 - 26.1.2 (on 1.21.1 cables may render wrong with Sodium; the author suggests Embeddium).
Compact redstone circuits for the whole group: add it to your Minecraft server via the panel in one click.
