BookFusion iOS 1.39.2 – Multi Window Support, Instant Highlights & More

This release focuses on enhancing the reading experience and boosting productivity while also delivering a feature many of you have requested.

What’s New

Multi Window Support – Multitasking & Parallel/Simultaneous Reading

Apple introduced multi-window capabilities with iPadOS and macOS to empower users to do more—fluidly and efficiently. BookFusion is now leveraging this capability to deliver a true multitasking reading experience.

Whether you’re reviewing class notes alongside a textbook, referencing a footnote in another edition, or reading fiction and nonfiction in parallel, BookFusion now adapts to how you want to read.

Run Multiple BookFusion Windows at Once

You can now launch and run multiple instances of BookFusion simultaneously on iPadOS and macOS. Dive into more than one book, document, or highlight stream at a time—just like having multiple tabs open in your browser.

Open Books Side by Side

Reading two books at once? Comparing different editions or translations? Simply drag a book from your bookshelf to the side of the screen to open it in a new window. This works beautifully with Split View on iPad or in full multitasking mode on macOS.

Launch from the Context Menu

Press and hold (long press) on a book cover and select “Open in New Window” from the context menu to instantly view that book in a separate window. It’s intuitive, fast, and designed to keep you in your flow.

View Highlights & Books Simultaneously

Keep your notes and highlights visible in one window while reading in another. This is especially useful when reviewing annotations, studying, or working with highlights in academic and professional settings.

Effortless Book Switching

You can now quickly switch between books across multiple windows without navigating away from your current page. Every book remembers where you left off, so you can jump back and forth without losing context.

Instant & Smarter Highlighting

Highlighting just got faster—and smarter. Now you can make Instant Highlights using your finger, not just your Apple Pencil. Annotate faster and stay in the flow, whether you’re reading in bed or jotting notes on the go. Just open the book you want to read head to Settings(A) → Instant Highlight to turn it on.

Highlights are now smarter too. We preserve the full meaning and structure of what you select: sentences include their punctuation, and paired symbols—like quotation marks and brackets—stay together automatically. No more broken highlights. Just clean, precise annotations every time.

Bookshelf Navigation Update

• Persistent Filters & Searches: Your filters, search terms, and list selections are now preserved during bookshelf refreshes.
• Resume Where You Left Off: The app now launches directly into your previously selected bookshelf list.

Enhanced Reading Experience

• New Spread Mode Option: Choose whether spreads start on odd or even pages—perfect for pdfs, comics, manga, and magazines.

• Auto Column Mode: Tap the active column setting to toggle Auto Column—automatically switches to single column in portrait and two columns in landscape for optimal reading. Readers can still choose to enable two columns in portrait mode if they prefer when reading on an iPad.

Fixes

• Improved formatting of book descriptions. Now supports clearer list items and additional paragraph spacing
• Fix for replacing book file with another book format
• Empty fixed EPUB pages after returning from background
• Other minor fixes

What’s Next?

This update is another step forward in providing the very best reading experience for readers.

We know from our last post that many of you are especially excited about dedicated reading statistics. Although that feature is not part of this release, it is in the pipeline :). The good news is that we have already completed significant backend work to track detailed statistics, and those APIs are now implemented in the iOS app. Once we start the UI/UX and a few additional API endpoints, you’ll be able to see your in-depth reading stats. For now, just keep reading , you will be able to explore your reading stats later this year. In the meantime, we hope you enjoy the improvements in this update.

We’re always working to make your reading experience better. You can grab the latest update from the App Store . If you haven’t already, we’d deeply appreciate a review on the App Store. It helps us grow and keeps the updates coming. Have feedback or need help? Reach out anytime to our support team. We’re here for you.

Happy reading!
