Suggestions and more shall be posted in the comments but as of now I will give some of my own I think the "Gonna wanna, and dis" replaced with going want and this should be removed it has many complaints. A plugin (I believe that's what it is) where you can sit on stairs would be nice A way to get rid of the scoreboard on the side and the big plot owner thing that pops up. Any further suggestions shall be in the comments.
I agree with your suggestions but wanted to add their is already a Suggestion page, setup for creative located here: https://aemservers.net/threads/official-creative-suggestion-thread.7611/
