I want to post a few suggestions for creative because i think that they could/would fit in.
The armor stand art plugin, its been added to slimefun and maybe survival soon. Getting this is creative could be really cool, maybe have a limit of say 25-50 per chunk or plot.
/sit and a new /crawl, the /sit could allow people to be in the builds and maybe screenshot and put them on discord. /crawl would be new and personally would like to see in all 4 servers like /sit, the crawling would be like when you get stuck in a 1by1 hole, how this would be made I dont know but I think i'd be cool.
/p set gravity true/false, this would let blocks with gravity either keep the gravity or have it disabled. A small setting that I personally could use.
World edit not working with bedrock, I believe its a bug and I hope it gets solved but players that are not builders/staff cannot world edit with bedrock (or atleast I cant :I)
