Client Features

These features run only on the client, and their settings are stored on your computer.

Compact status effects

The status effects next to the inventory and creative inventory shrink to one small icon showing how many beneficial and harmful effects you have; hovering over it expands the full list.

mini_effects_client.toml:

Option Description
effectsOnLeft Show on the left side of the inventory
requiresHoldingTab Show only while Tab is held
potionItemIcon Use a potion bottle instead of effect icons in the compact view

Hidden while the recipe book is open. With JEI installed, JEI's item list stays clear of it.

FPS and TPS/MSPT HUD

Shows your FPS and the server's TPS and MSPT on screen. In F6 you can switch them on or off, scale them and drag them with a visual editor. Turning the TPS HUD off also stops the server from sending you samples.

Startup info

Shows the game's startup time and the logged-in account (startup.toml).

Copying items

  • Alt + C: copy the ID of the held or hovered item.
  • Alt + F: show item details (including components/NBT).

Works on items inside containers too.

Log cleaning

log_cleaner.toml:

Option Default Description
enable true Remove old logs and crash reports when the game closes
errors_only false Log only ERROR/FATAL lines
filtered_keywords Lines containing these keywords are not logged at all; separate several with commas
max_logs / max_debug_logs / max_crash_reports 3 How many old files of each kind to keep

Repeated log lines are kept individually. The obsolete deduplication setting is removed automatically when the configuration loads.

Default client options

In F6, export your current game settings as defaults. New option files (for example a modpack player's first launch) then start from these defaults.

Other improvements

  • The narrator is fully disabled.
  • No experimental-features warning when creating a world.
  • The "unverified server" popup becomes a chat message.
  • Deleted worlds go to the system recycle bin (general.toml → recycleBinWorlds).
  • The recipe book can be removed for faster loading and less memory (general.toml → removeRecipeBook).
