[Feature Request]: Improve PDF Viewer with a dedicated View mode and fullscreen reading experience

Feature Description

I would like to request a more complete and dedicated View/Reading mode for the PDF viewer.

The viewer should provide a clear "View" or "Reading" experience focused on reading the document rather than editing or processing it.

Useful controls could include:

• Enter/exit fullscreen
• Zoom in/out
• Fit to width
• Fit to page
• Page navigation
• Single-page view
• Continuous page view
• Rotate
• Search within the PDF
• Show/hide thumbnails
• Show/hide toolbars
• Optional distraction-free reading mode

The toolbar should ideally be able to automatically hide while reading and reappear when the mouse is moved or when the user presses a shortcut.

Why is this feature valuable?

Stirling-PDF is increasingly capable of being used as a general PDF viewer/editor, but the reading experience could be more focused.

When reading a PDF, users often want to maximize the available screen space and remove unnecessary UI elements.

A dedicated fullscreen/distraction-free reading mode would be especially useful for:

• Books
• Technical documents
• Research papers
• Educational material
• Presentations
• Large PDFs

Suggested Implementation

A dedicated View mode could provide a compact toolbar with the most important reading controls.

Fullscreen could use the native desktop fullscreen functionality where available.

Keyboard shortcuts could also be supported, for example:

• F11 → fullscreen
• Esc → exit fullscreen
• Ctrl + F → search
• • / - → zoom

Additional Information

The goal is not necessarily to copy another PDF reader, but to provide a clean and efficient reading mode within Stirling-PDF.
