Kit Editor Skript

[terse mica]

yep, definitely possible
i'd imagine it wouldn't be very difficult using a list, which will retain its order

[ornate marsh]

absolutely possible, if you want to make it easier on yourself, you can have a look at Shane's inventory serializer snippet for saving the kits and creating your own guis for making them!

GUIs

What are GUIs?

GUIs are custom inventories that you can use from all sorts of purposes including shops and server selectors. There are two main ways to create them, using normal Skript and using the addon skript-gui

Vanilla GUIs

skript-gui

Before you start making GUIs with skript-gui, you will have to download the addon here
Once you are ready to begin, Click Here to get started!
This addon simplifies some of the steps of making GUIs such as listening for clicks

Tuske

Tuske is an old addon used for creating GUIs. It has become very outdated and will break all of your code. If you still have this addon installed please switch to skript-gui

Honestly, i would just place items in my own inventory and then use the inventory serialiser
