# UI/UX Improvements Documentation

## Overview

This document describes the user interface and user experience improvements implemented in the Survey Custom Certificate Template module to enhance usability and provide better feedback to users.

## Implemented Improvements

### 1. Progress Indicators

#### Visual Progress Bar
**Location**: Wizard header (form view)

**Features**:
- Three-stage progress indicator showing:
  1. ✓ Template Uploaded
  2. ✓ Placeholders Detected
  3. ✓ Preview Generated
- Color-coded badges:
  - Green (✓): Completed steps
  - Gray (○): Pending steps
- Always visible once template is uploaded
- Provides clear visual feedback on workflow progress

**Benefits**:
- Users know exactly where they are in the configuration process
- Reduces confusion about next steps
- Provides sense of accomplishment as steps complete

### 2. Enhanced Error Messages

#### Clear, Actionable Error Messages
All error messages follow a consistent pattern:

**Structure**:
```
[What went wrong]

[Why it happened]

[What to do next]
```

**Examples**:

1. **File Upload Errors**:
   ```
   The uploaded file is not a valid DOCX file or is corrupted.
   
   Please ensure you are uploading a Microsoft Word (.docx) file.
   You can create DOCX files using Microsoft Word or LibreOffice Writer.
   ```

2. **LibreOffice Errors**:
   ```
   PDF conversion failed: LibreOffice is not installed.
   
   LibreOffice is required to convert certificates to PDF format.
   System administrators have been notified.
   
   Please contact your system administrator to install LibreOffice.
   ```

3. **Validation Errors**:
   ```
   Template file exceeds the maximum allowed limit of 10MB.
   
   Large files can cause performance issues and slow down certificate generation.
   
   Please reduce the file size by:
   • Compressing embedded images
   • Removing unnecessary formatting
   • Simplifying the template design
   ```

#### Error Message Categories

| Category | Color | Icon | Example |
|----------|-------|------|---------|
| Validation Error | Red | ⚠️ | Invalid file format |
| System Error | Orange | 🔧 | LibreOffice unavailable |
| User Error | Yellow | ℹ️ | Missing required field |
| Success | Green | ✓ | Template saved successfully |

### 3. Loading Indicators

#### Button Confirmation Dialogs
**Implementation**: `confirm` attribute on action buttons

**Features**:
- Confirmation dialog before long-running operations
- Clear description of what will happen
- Prevents accidental clicks
- Sets user expectations for wait time

**Examples**:
```xml
<button name="action_upload_template" 
        confirm="This will analyze your template and extract all placeholders. Continue?"/>

<button name="action_generate_preview" 
        confirm="This will generate a sample certificate with test data. This may take a few moments. Continue?"/>

<button name="action_save_template" 
        confirm="This will save the template and mappings to your survey. Certificates will be generated using this configuration. Continue?"/>
```

#### Visual Feedback During Operations
- Odoo's built-in loading spinner appears during server operations
- Form is disabled during processing to prevent duplicate submissions
- Clear success messages after completion

### 4. Contextual Help

#### Inline Help Text
**Location**: Throughout the wizard form

**Features**:
- Field-level help tooltips (hover to see)
- Section-level guidance (always visible)
- Step-by-step instructions
- Examples and best practices

**Examples**:

1. **File Upload Section**:
   ```
   Upload a Microsoft Word (.docx) file with placeholders in the format {key.field_name}.
   Examples: {key.name}, {key.course_name}, {key.date}
   Maximum file size: 10MB
   ```

2. **Placeholder Mapping Section**:
   ```
   Configure how each placeholder should be filled:
   • The system has automatically suggested mappings for recognized placeholder names
   • You can change the Value type and Field for each placeholder
   • Drag rows to reorder placeholders
   ```

3. **Preview Section**:
   ```
   This preview uses sample data. Actual certificates will use real participant information.
   ```

#### Help Section for New Users
**Location**: Bottom of wizard (visible when no placeholders detected)

**Content**:
- Getting Started guide
- Step-by-step workflow
- Link to full documentation
- Common troubleshooting tips

### 5. Visual Enhancements

#### Icons and Emojis
Strategic use of icons to improve scannability:

| Element | Icon | Purpose |
|---------|------|---------|
| Steps | 📄 🔧 👁️ | Identify workflow stages |
| Actions | 📤 💾 ❌ | Clarify button purposes |
| Placeholders | 📍 | Identify placeholder fields |
| Data Types | 🔄 📊 ✏️ | Distinguish field types |
| Alerts | ✓ ⚠️ ℹ️ 💡 | Categorize messages |

#### Color-Coded Alerts
**Bootstrap Alert Classes**:
- `alert-success` (Green): Success messages, confirmations
- `alert-info` (Blue): Informational messages, tips
- `alert-warning` (Yellow): Warnings, important notes
- `alert-danger` (Red): Errors, critical issues

#### List Decorations
**Placeholder Mapping Table**:
- `decoration-info`: Highlights custom text entries in blue
- Alternating row colors for better readability
- Hover effects for interactive elements

### 6. Improved Button Labels

#### Before and After

| Before | After | Improvement |
|--------|-------|-------------|
| "Upload" | "📤 Parse Template" | Clearer action |
| "Preview" | "👁️ Generate Preview" | More descriptive |

| "Discard" | "❌ Cancel" | Standard terminology |

#### Button Styling
- Primary actions: `btn-primary oe_highlight` (blue, prominent)
- Secondary actions: `btn-secondary` (gray, less prominent)
- Destructive actions: `btn-danger` (red, for deletions)

### 7. Smart Defaults and Auto-Suggestions

#### Automatic Field Mapping
**Feature**: System automatically suggests mappings for common placeholders

**Recognized Patterns**:
- Name variations: `{key.name}`, `{key.student_name}`, `{key.fullname}`
- Email variations: `{key.email}`, `{key.user_email}`
- Date variations: `{key.date}`, `{key.completion_date}`

- Prevents common mapping errors
- Provides learning examples for users

#### Update Mode Preservation
**Feature**: When updating templates, existing mappings are preserved

**Implementation**:
- Alert banner notifies user of update mode
- Matching placeholders retain their mappings

### 8. Responsive Feedback
