Enhancing Edovo’s PDF Reader: Essential Features for Meaningful Access and Engagement

For app developers and correctional educators working with Edovo’s online learning platform, the current PDF reader offers a basic foundation but falls short of providing a truly effective reading experience. The existing tool allows users to flip through pages sequentially, jump to a specific page by number, and access a table of contents. However, these features are minimal and leave significant room for improvement—especially in the context of Edovo’s mission to promote education, engagement, and digital literacy in correctional settings.

In this article, we will explore how expanding the PDF reader’s functionality can unlock meaningful access to educational content, foster deeper engagement, and empower users with digital skills that extend beyond the classroom. We will also recommend open source solutions that could be integrated into Edovo’s web app, saving development resources while maximizing impact.

Why Minimal Features Limit Learning and Engagement

Edovo’s current PDF reader enables only the most basic navigation: moving forward and backward page by page, jumping to a numbered page, and browsing a flat table of contents. While these are essential building blocks, they do not meet the needs of users who want to interact with content in ways that enhance comprehension and retention.

For example, the table of contents, though present, is poorly designed. It is displayed as a flat list rather than a hierarchical outline that reveals chapters, subchapters, and nested sections. This limits a learner’s ability to understand the structure of the material and to quickly navigate through complex documents. Worse, the table of contents currently covers the entire reading pane, obscuring the page itself and disrupting the reading flow. This creates a frustrating user experience and diminishes the learner’s connection with the text.

Moreover, the page number navigation feature is difficult to find, which means many users may not realize they can jump to specific parts of the text. Combined with the absence of essential tools such as search, zoom, highlighting, bookmarking, and annotations, the reader is missing opportunities to support active learning and digital literacy development.

The Case for Feature-Rich PDF Readers in Correctional Education

Adding well-considered featuresthe PDF reader will directly contribute to Edovo’s educational mission by making content more accessible and interactive.

Search Functionality

Search allows users to quickly locate keywords or phrases within a document, saving time and helping learners engage with specific topics or questions of interest. In correctional education, where learners often have limited study time, search enables efficient review and supports self-directed learning.

Bookmarking and Highlighting

Bookmarks let users mark important pages or sections to revisit later, while highlighting allows them to visually emphasize key passages. These tools encourage active reading strategies, which research shows improve comprehension and retention. They also foster a sense of ownership and engagement with the material.

Annotation and Note-Taking

Annotations enable users to add personal comments, questions, or summaries alongside the text. This not only deepens understanding but also creates a record of thought processes that educators can review or reference. For incarcerated learners, building annotation skills supports critical thinking and academic habits that translate to broader educational success.

Zoom and Accessibility Features

Zooming in on text improves readability for users with visual impairments or those using small screens. Accessibility features like text resizing and screen reader compatibility ensure the platform is inclusive and meets diverse needs.

Improved Table of Contents and Navigation

Replacing the flat, obtrusive table of contents with an expandable, hierarchical sidebar that coexists alongside the reading pane would allow users to navigate intuitively without losing sight of the content. Additionally, more visible and intuitive page navigation controls will help users move through texts confidently.

Support for Hyperlinks

Many PDFs contain hyperlinks to internal references or multimedia content. Supporting clickable links enhances the learning experience by connecting learners to related information, tables, and figures.

Recommended Open Source PDF Readers for Integration

Instead of building from scratch, Edovo can leverage mature open source PDF readers that already incorporate these features. One notable option is PDF.js, a Mozilla-led project widely used in web applications. PDF.js supports zooming, search, annotations (through extensions), and flexible navigation panels. It is highly customizable, enabling Edovo to adapt the UI to its unique needs, such as designing a non-obtrusive, hierarchical table of contents.

By integrating a reader and customizing it for Edovo’s platform, developers can rapidly enhance usability and functionality, giving learners a more powerful and enjoyable reading experience.

Conclusion: Elevating Edovo’s Impact Through Better PDF Readers

Improving Edovo’s online PDF reader is not just a technical upgrade—it is a strategic step toward realizing the organization’s core mission. By incorporating search, bookmarking, highlighting, annotation, zoom, and better navigation, the reader will transform from a passive viewer into an active learning tool. This empowers incarcerated learners to engage more deeply with educational content, develop critical digital literacy skills, and build habits that support lifelong learning.

For developers and educators invested in correctional education, focusing on these reader enhancements offers a tangible way to support learners’ success and foster meaningful educational opportunities behind bars.
