Enhancing the OCR interface by developing a scroll bar to view all captured pages—instead of relying on an arrow button to navigate one page at a time offers key benefits:

1. Improved User Experience

Faster Navigation: Users can quickly scroll through multiple pages without repeatedly clicking arrow buttons.

More Control: A scroll bar allows users to jump to any part of the content instantly, rather than moving sequentially.

Intuitive Design: Scrolling is a familiar and natural interaction pattern for most users.

2. Increased Efficiency

Timesaving: Reduces the time spent navigating, especially when dealing with a large number of pages.

Better Overview: Users can get a sense of the total content at a glance, which is helpful for reviewing or comparing pages.

3. Accessibility and Inclusivity

Keyboard and Mouse Friendly: Scroll bars are accessible via keyboard shortcuts and mouse wheels, improving usability for users with different preferences or needs.

Assistive Technology Compatibility: Scrollable interfaces are generally more compatible with screen readers and other assistive tools.

4. Scalability

Handles More Content Gracefully: As the number of captured pages grows, a scroll bar remains efficient and user-friendly, unlike arrow buttons which become cumbersome.
