BetterChat

A Minecraft Forge mod for 1.8.9 that completely replaces the default chat with a powerful, customizable, multi-tab chat system.

Create as many chat tabs as you want, each with its own filter settings
Double-click a tab to rename it
Right-click a tab to delete it (confirm with a second right-click)
Drag tabs to reorder them within a window, just like a browser
Drag tabs out of the window to spawn them as their own independent floating window
Drag tabs onto another window to merge them back together
Click [+] to add a new tab at any time

Multiple chat windows open simultaneously

Every tab has its own independent filter configuration, letting you build a chat layout that only shows what you care about:

Inclusion keywords — only show messages that contain at least one of these words (comma-separated). Useful for a specific player's name, a server channel prefix, or a keyword like trade
Exclusion keywords — always hide messages containing these words, even if they pass the inclusion filter. Great for muting spam or specific players
Include All Messages — bypass all filters and show everything on this tab, useful for a dedicated "Global" tab
Include Player Messages — show chat from other players (messages in <name> format)
Include Server Messages — show system/server messages that aren't from players (join/leave messages, announcements, etc.)
Include Commands — show commands you type (messages starting with /)
Include Command Responses — show server responses to commands you ran within the last few seconds
Prefix / Suffix — text automatically added before/after every message you send from this tab. For example, a prefix of [Trade] lets you type naturally while always tagging your messages

Exclusions are checked first, then inclusions. Your own messages always appear on every tab regardless of filters.

All chat messages are saved to disk and persist across sessions — your full history is always there when you log back in
History is shared across all tabs — each tab just filters the same global log differently, so no messages are ever lost
Date separator bars are shown inline whenever the date changes, so you can always tell when a conversation happened
Chat always jumps back to the latest messages when you open it
History saving can be toggled off in settings if you prefer a clean slate each session

The scroll bar represents only the current day's messages — always a comfortable, usable size no matter how much history you have
▲ / ▼ arrows appear on the scroll bar to jump between days
The date (MM/DD) is shown next to the arrows when browsing older history

Open the settings panel (⚙ gear icon on any window) to customize:

Colors & Opacity

8 individually configurable color slots: tab selection bar, top bar, background, text, timestamps, input bar, and both HUD fade overlay colors
Each slot has its own fully independent color and opacity setting
A full HSB color picker per slot — hue ring, saturation/brightness square, live preview swatch, opacity slider, and direct hex code input

Toggles

Timestamps — shows HH:MM next to each message on the right side
Unread notification dots — a colored dot marks any tab with unseen messages
Save chat history — disable if you don't want messages persisted to disk
Lock position — freezes all windows in place so they can't be accidentally moved or resized
Reset to defaults — restores all colors and toggles to their original values

Per-Tab Settings (accessible from the Filters page)

Configure inclusion/exclusion keywords, message type toggles, and prefix/suffix per tab, all from one panel

Colors and Style settings panel HSB Color picker with hue ring, opacity slider and hex input
