For example:
• Fences- I tried making them and they didn't work, I looked it up and I got the same crafting recipe that I had used...
• To commands- Whenever my friends and I go exploring, we always have to end up dying to go back to spawn. Also if we die, we can't go back to the person who was near our death.
• /Set home- Its really important, if we go somewhere and we forget something you could always have back up. You could also use that command if you get lost, etc.
• /Spawn- This could probably be the most useful. You could use it the same way as /Set home. Also, people could use that command to trade, sell, and other stuff like that.
These things are just some suggestions, if there are any comments I would love for you to tell me!

Thanks for taking the time to read this!
