Craftbook is a server side mod that lets the player simplify complex redstone by using a simple sign with text.
The main wiki for the mod is https://craftbook.enginehub.org/en/3.x/
Not everything from Craftbook is included in the server, that would be an overpowered mess for a survival server... but you can do MANY things.
Using a Repeater from Integrated Circuits to extend some redstone to activate a netherrack block to light it abalze
Create an item sorter!
Easy to use - minimal redstone required! Use the Pipes plugin from craftbook to quickly move items between chests and do some basic sorting. For more advanced sorting, use pipes in combination with [MC1229] "sorter" from Integrated Circuits.
I dunno, turn on your oven, but only if you have some ham in your pockets?
Use the Player Inventory Sensor to detect if a nearby player has raw pork in their inventory slot1, then use that to trigger redstone to activate fire on some netherrack
