config.yml reference

plugins/QuickBuy/config.yml controls the auction hook, buy limits, the item picker and the GUI layout. Every player-facing string lives in messages.yml (MiniMessage).

Hook & buying

auction-hook: AUTO        # AUTO | CRAZY | AX | ZAUCTION | ZEL | PLAYER
max-per-purchase: 64      # max items one favourite click can buy
price-refresh-seconds: 0  # auto re-read prices while open (0 = on open + Refresh only)
strict-item-match: false  # true = require full meta/NBT match for plain favourites
skip-own-listings: true   # don't buy your own listings when buying the cheapest

Key	Default	Meaning
auction-hook	AUTO	Which auction plugin to drive; AUTO detects it.
max-per-purchase	64	Cap on items bought per favourite click.
price-refresh-seconds	0	Auto price refresh interval while the GUI is open.
strict-item-match	false	false matches by item type (plus chosen enchants); true requires identical meta.
skip-own-listings	true	Skip your own listings when buying the cheapest.

The item picker

choose-item:
  mode: DIALOG            # DIALOG | GUI | AUTO
  dialog-min-protocol: 771  # AUTO falls back to GUI below this (771 = 1.21.6)
  page-size: 100
  icon-format: "<name>"

Key	Meaning
mode	DIALOG uses the native dialog with inline atlas icons (no resource pack); GUI is the inventory fallback (real icons, every version); AUTO picks per client.
dialog-min-protocol	Clients below this protocol get the GUI (needs ViaVersion to detect older clients).
page-size	Items per page in the dialog picker.

GUI & sell slots

The whole gui: block sets each menu’s title, filler material and the slot + material of every control button (Quick Buy, Choose, Your Items, Transactions, Insert). The sell board is configured here too:

gui:
  click-cooldown-ms: 100        # debounce for menu buttons (anti double-click)
  your-items:
    default-slots: 18           # sell slots a normal player gets
    donutplus-slots: 45         # slots granted by quickbuy.donutplus
    pages: 2
    slot-permissions:           # permission -> slot count (highest wins)
      quickbuy.slots.27: 27
      quickbuy.slots.36: 36

Key	Default	Meaning
gui.click-cooldown-ms	100	Minimum ms between registered button clicks (stops macro double-fires).
your-items.default-slots	18	Sell slots for a normal player.
your-items.donutplus-slots	45	Slots granted by quickbuy.donutplus.
your-items.slot-permissions	—	Map a permission node to a slot count; see Commands & permissions.
