Implement continuous mode for scrolling

Feature Request: Implement Continuous Scrolling Mode

Is your feature request related to a problem?

Currently, Foliate only supports paginated navigation but many users prefer continuous vertical scrolling for long reading sessions, as it provides:

• Smoother reading flow without visual interruptions
• Better context retention through seamless text progression
• Natural navigation similar to web browsers/PDF readers
• Reduced cognitive load from not managing "page turns"

Proposed Solution

Add a new "Continuous Scroll" mode accessible through:

1. View Menu: New "Continuous Scrolling" toggle option
2. Keyboard Shortcut: Configurable shortcut (e.g., Ctrl+Shift+C)
3. Toolbar Button: Optional scroll icon next to existing view controls

Why is this feature important?

1. User Preference: A significant number of readers prefer scrolling over pagination.
2. Accessibility: Reduces friction for users with motor impairments
3. Workflow Efficiency: Enables faster navigation through search-driven reading

Additional Context

• Existing Alternatives: Document Viewer (Evince) demonstrates successful implementation

Note: This would complement rather than replace existing pagination options.

Agreed. This is particularly important for PDF books, as relative page size is fixed and zooming with PDFs (once Foliate supports it) can only accomplish so much.

yes let's hope it happens

Does the existing "Scrolled mode" accessible from the reader menu do what you're looking for?

I can’t speak for any of the other file formats, but for PDFs the “Scrolled mode” simply prevents the scroll wheel from doing anything (whereas without “Scrolled mode”, the wheel would at least turn the page).
