Command Block Condenser
This tool lets you bundle a bunch of commands into a single command and wrap it all up in a clean, colorable case. It’s meant to make messy setups simpler. If you don’t feel like building your own from scratch, Modplace is there for grabbing ready-made command mods and just using them. I included a "command mod" so you can try it out, see how things work, and maybe experiment a bit. Note: Things may break if you activate it in any way other than using a lever on the side, so maybe don’t tempt fate.
Modplace
If you aren’t fluent at commands or don’t know too much about them, you could use the Modplace! A spot to get command block mods made by other people! And if you can write command mods, you can deploy your own to it too!
