Suggestions

E-books

Let E-books be stackable

Spawner Extractor

Add the Phantom and the Phantom Membrane to the Spawner Extractor.

Wither skeleton skull

Add the Wither skeleton skull to the spawnerextractor.

ChunckRipper

Maybe add an option with chunckrippers that you can choose between keeping the stuff you've made or rip everything in that chunck.

Soul Harvester

Add the enchant 'Soul Harvester' to swords

XP farm

Make it so you can kill chickens when being spawned in a XP spawn while there is a mob riding it.
Right now you'll get spammed with 'that belongs to <name>'

Shulkers

I have 2 suggestons:

1) Please, make it so when we dubble-click on shulker that it will auto-sort itself.

2) Make it when you put a shulker in your itemfilter that it'll take all shulkers, not just the empty ones.

Disable/Enable MobSpawn

Make a command that you can disable your spawners when you try to modify your farm.
So like this:
/Disablemobspawn (Or just /Disablemb or something like that)
And to enable:
/Enablemobspawn (Or just /Enablemb or something like that)
This would be very helpful

Name tag

Add the item 'Name Tag' to /shop

/itemfilter

Maybe change it a little bit by adding an option to filter-out the items you don't want to collect instead of the items you do want to collect, then let players choose which one they'll activate.

Search function

Make a search function in /quest so it is easier to find that specific quest.

/unsmelt (all)

I've recently posted this: https://www.extremecraft.net/suggestions/view/11124/ (/uncraft)
It would also be nice if there is something like /unsmelt

/uncraft

It would be nice if there is a command to uncraft items.
I myself make this mistake very often that I craft too many items without my intending to do so, sometimes that's very annoying (And dumb, I should pay attention ofc)

Dropparty

Disable the use of potions when there is a dropparty, many ppl won't agree with me, but I think it's a bit unfair to others who doesn't use potions like jumpboost or speed.

Brake boats

Make it so you are able to break your own boat when u've ended up in someone's warp.

Pressure plates

Please, disable the 'Hey! Sorry, but you can't use that here.' msg from spawn when walking on those Pressure plates, it's very annoying and it's spamming the chat.

Chests

Idk if this is actual doable but let's give it a try ;)

Make it that we are able to dye chests cuz that would be lovely when building things.
chests are kinda ugly and boring cuz it's always the same ofc

/Pwarp favo

Make is possible to set a Pwarp as your Favorite so you don't have to search for that specific pwarp.
So when you do /pwarp that there comes an item special for your Favorite pwarp's.

/wild

It would be nice that if you do /wild, you will not teleport in some his/her claimed land, often when I do /wild I land in a claimed land and then you can't do anything for example: mining.

I hope you understand what I mean cuz i'm not that great in explaining things :x

Crates Shortcut

When you've voted you'll get the message: [Crates] >> You Received 2x [vote key]!
If would be nice that if you click on the 'Crates' part you'll be teleported to the Crates warp.
