Addendum: Stasis Chambers and an Idea.

Some nice concepts you are showing here. Ender pearl stasis chambers are underrated imho. I feel like I am the only one using them and they're really handy especially on multiplayer servers

I never thought to use leaf block updates, and as you say they are super flexible when you need to cut corners or move up or down. I can also see myself using the two way instant wire solution and just have one line going back and forth. I also saw Tangos vid but never thought to use the wire in an ender porter. I really like your idea of the bullet train stations with the token dispensers. Hmm, thoughts be brewing, my main problem is what to focus on lol Too much jumping back and forth between projects can be counter productive to me. But I'll keep these solutions in mind while building my tunnel and then integrate the ender porter system into it afterwards.

If someone builds this I’d love a tutorial for it~!! Can even build around it to make it look like a bullet train~!!
