+# Enhanced Terminal v3.0 - Changes and Improvements
+
+## 🎉 Major New Features
+
+### 1. Command History Search (Ctrl+R / Cmd+R)
+**Status:** ✅ Fully Implemented
+
+**What it does:**
+- Fuzzy search through entire command history
+- Visual panel with searchable list
+- Instant results as you type
+- Double-click or Enter to use a command
+
+**Implementation:**
+- `HistoryManager.swift`: Manages command history with fuzzy search
+- `Panels.swift`: `HistorySearchPanel` class with table view
+- Keyboard shortcut: Cmd+R
+- History persists between sessions (UserDefaults)
+- Maximum 1000 commands stored
+
+**Technical details:**
+- Uses `NSTableView` for display
+- `NSTextFieldDelegate` for live search
+- Case-insensitive fuzzy matching
+- Prevents duplicate consecutive commands
+
+### 2. Multiple Tabs
+**Status:** ✅ Fully Implemented
+
+**What it does:**
+- Open multiple terminal sessions in tabs
+- Each tab has independent shell process
+- Easy tab switching with mouse or keyboard
+- Visual tab bar at top of window
+
+**Implementation:**
+- `TerminalSession.swift`: Individual terminal session management
+- `TabManager` class: Manages multiple sessions
+- `MainWindowController.swift`: Tab bar UI and switching logic
+- Keyboard shortcuts: Cmd+T (new), Cmd+W (close)
+
+**Technical details:**
+- Each tab runs separate `Process` for zsh
+- Independent `inputPipe` and `outputPipe` per tab
+- Tab bar uses `NSStackView` with dynamic buttons
+- Proper cleanup on tab close to prevent memory leaks
+
+### 3. Auto-Suggestions (Fish-shell style)
+**Status:** ✅ Fully Implemented
+
+**What it does:**
+- Shows command suggestions as you type
+- Based on command history
+- Gray text overlay showing completion
+- Press Tab to accept suggestion
+
+**Implementation:**
+- `TerminalSession.swift`: Suggestion logic and display
+- `HistoryManager.swift`: `getSuggestion()` method
+- `Settings.swift`: Toggle setting
+- Visual overlay using `NSTextField`
+
+**Technical details:**
+- Suggestion label positioned at cursor
+- Uses `NSLayoutManager` for precise positioning
+- Filters suggestions based on partial input
+- Theme-aware suggestion color (semi-transparent)
+
+### 4. Split Panes
+**Status:** ⚠️ Planned (UI framework ready, not yet implemented)
+
+**What's ready:**
+- Menu items created
+- Keyboard shortcuts defined (Cmd+D, Cmd+Shift+D)
+- Placeholder methods in `MainWindowController`
+
+**What's needed:**
+- Split view container implementation
+- Pane management logic
+- Resize handles
+- Focus management between panes
+
+**Note:** The foundation is in place for future implementation.
+
+### 5. Better Shell Integration
+**Status:** ✅ Fully Implemented
+
+**Improvements:**
+- Fixed "fg: no job control in this shell" messages
+- Cleaner prompt display
+- Better environment variable handling
+- Improved ANSI escape code filtering
+
+**Implementation:**
+- Changed shell arguments from `-i` to `-l` (login shell)
+- Better environment setup in `TerminalSession.swift`
+- Enhanced ANSI cleaning with more patterns
+- Proper `TERM` variable set to `xterm-256color`
+
+**Technical details:**
+```swift
+shellTask?.arguments = ["-l"]  // Login shell
+env["TERM"] = "xterm-256color"
+env["DISABLE_AUTO_TITLE"] = "true"
+```
