Apple Books 12+

This app is great for book reading. Be it epub format or pdf. I also use it for journaling. Works great like an actual journal. My three requests are:
1) add multi window support on ipad so that i can open two books at once for reference.
2) if i highlight and add comments in a pdf, a box appear above the highlighted word which hides another word behind it and make it unreadable. Do something about it.
3) if possible please add option to insert images and stickers while annotating a pdf. It will drastically change the experience and be very helpful.

if you’re a student especially a medical student like myself, and using this books app to annotate and make side notes on your PDF by opening your PDF in the books app, please don’t! Use any other app instead. All of a sudden the app will crash and you wouldn’t be able to open the pdf anymore and you will lose all the valuable notes you’ve made. Mine happened weeks before my USMLE exams and i’ve lost my notes forever. I have learned from the reviews and online forums that many have experienced the same issue and no amount of troubleshooting steps have helped them recover any of it. I also contacted apple helpline and they weren’t able to help me either. Sadly no one will read this review before something like this happened because the app comes pre-installed on the ipad and it’s unlikely someone sees the rating before they face an issue.

I’m completely vexed up using books app and purchased recently other app for reading . I’m a student and brought iPad exclusively to study . But unfortunately I didn’t know about that this stupid books app is tooo worst. 2-3hours of written notes gets vanished all of a sudden . Whole effort goes in vain. This happens more often . No problem with the iPad as it’s brand new AIR 4. Only problem is the books app . Sometimes it doesn’t open at all . I’m a doctor and in case of emergency to refer a book it never responds timely and doesn’t even open well . Apple need to improve a lot with this app . Features are very good but these sudden added written text getting lost and app not opening on sometimes making this app the worst of its kind .
