Request: Allowing PDF files to be Incrementaly Reviewed

**Appreciation**

Firstly, I'd like to express my sincere appreciation for the fantastic work done on creating this plugin. It's been an invaluable tool for enhancing the writing experience, and its seamless integration has significantly improved my productivity.

**Request for PDF Review Feature**

While the plugin has proven to be incredibly effective for writing incrementaly, I would like to propose an enhancement to further expand its utility. Many of us often need to review and annotate incrementaly or PDF documents as part of our writing process.

That's why the implementation of PDF review functionality allows users to review their documents incrementally, seamlessly integrating with their writing process and the plugins within Obsidian Software.

Thank you once again for your dedication to continuously improving this plugin. I look forward to the possibility of seeing this feature implemented in future updates.

The request names no files, tests, or existing entry points. Start by examining the plugin's current review workflow and Obsidian document integration, then define the supported PDF review scope and acceptance criteria before implementation; the issue does not specify a concrete PDF workflow.
