# Session Summary - October 3, 2025 (End of Day)

## Overview
Today's session focused on implementing comprehensive filtering enhancements across all view modes and refining the visual feedback system.

---

## 🎯 Completed Features

### 1. Button-Triggered Filtering ✅
**Problem**: Filters applied in real-time while typing, causing performance issues and unwanted filtering during text entry.

**Solution**: 
- Removed `.trace()` callbacks on filter variables
- Added **"🔍 Apply"** button to all filter panels
- **Enter key** in filter fields triggers apply
- Status dropdown still auto-applies (standard UX)

**Impact**: Better user control, improved performance, clearer workflow.

---

### 2. Filter Panel in Document View ✅
**What Was Added**:
- Complete filter UI at top of Document View
- Mode toggle buttons (🔍 Filter / 💡 Highlight)
- Source, Target, and Status filter fields
- Apply and Clear buttons
- Results counter

**Features**:
- Shares filter state with Grid and List views
- Filters persist when switching views
- Consistent UX across all three view modes

**Location**: Lines 1596-1710 in `cat_editor_prototype.py`

---

### 3. Filter Highlighting in Document View ✅ → Enhanced ✅
**Version 1 (Initial)**:
- Entire segments highlighted in yellow
- 2px border around matching segments
- Functional but visually overwhelming

**Version 2 (Improved - v0.4.1)**:
- **Only search terms** highlighted (not entire segments)
- Bright yellow background (`#FFFF00`)
- Bold font for emphasis
- Multiple occurrences all highlighted
- Works in both paragraphs and table cells

**Benefits**:
- Precise visual feedback
- See exactly what matched
- Context remains readable
- Professional appearance

**Location**: Lines 2791-2869 (new function), 1969, 2078 (calls)

---

### 4. Keyboard Shortcuts for Filtering ✅
**New Shortcuts**:
- **Ctrl+M** - Toggle Filter/Highlight mode
- **Ctrl+Shift+A** - Apply filters
- **Ctrl+Shift+F** - Focus source filter field
- **Enter** (in filter fields) - Apply filters

**Implementation**:
- Global bindings work in all views
- Helper functions for mode toggle and focus
- Integrated with existing shortcut system

**Location**: Lines 176-180 (bindings), 3855-3883 (functions)

---

### 5. Filter Preferences Saved to Projects ✅
**What Is Saved**:
```json
{
  "filter_preferences": {
    "mode": "filter",
    "source_filter": "contract",
    "target_filter": "",
    "status_filter": "untranslated",
    "active": true
  }
}
```

**Features**:
- Filter mode remembered
- Filter text preserved
- Status selection saved
- Active state restored
- Auto-apply on load
- 100% backward compatible

**Location**: Lines 4320-4335 (save), 4388-4414 (load)
