Books/iBooks app on iPad OS 13.1

I bought the iPad Pro for the single purpose of reading large textbooks and PDFs as it loads them very fast and smooth. Doing highlights, keeping annotations, bookmarks... and using Apple Pencil on PDFs. iBooks/Books app was the single purpose of buying an iPad because of its feature of self containing PDFs, and works done on them. I didn’t give a f*** about Oprah’s book club.

If I wanted to read PDFs by using files/folders directory I would have bought a Microsoft’s Surface not an Apple’s iPad.

Please be Apple with your exclusive features. Windows uses folders/file system to access PDFs, iBooks/Books self contains PDFs inside the App.

Please
