Item Editor [Abilities Update]

Abilities are here. Items can now do actions by themselves, easily accessible from the Editor menu or commands.

• Abilities, set up from /jstash:editor: a trigger (like on hit, kill, shoot, hurt, use, held, worn, mine or break), up to 8 steps, and optional chance, cooldown, conditions and costs
• 18 starting templates, in case you don't want to configure one from scratch
• Abilities on stackable items are available but due to a Script API limitation atm, they are off by default, turn it on under Abilities in /jstash:settings
• "Type any number" setting, for going past the slider limits
• /jstash:editor now takes a slot and a panel, so /jstash:editor @s mainhand abilities jumps straight to that menu
• Making a stackable item into a wand now tells you it needs an item that doesn't stack, instead of throwing an error

Documentation is now on the website: editor guide, command reference and abilities.

I have also built an item builder for putting together a /jstash:grant command for any item, just in case if you are too lazy to configure one yourself.
