In I believe in minecraft versions 1.13 and above, there is tab completion and command suggestions. I would love to have this in 1.8 and thats all. What I mean if you don’t know is where if I typed /execute in 1.16 and didn’t hit enter, it will bring up suggestions like “execute at”, “as”, or “in”. Then you can press the arrow keys up and down go select an option and it will auto complete the command with that word in it for you. I would love this in 1.8. Thank you!
