Is there an option for Paragraph breaking between pages (might be wrong term for it)

Okay, so one thing I would like to have is have the reader automatically detect when a paragraph will enter into the next page, so it always ends on the last complete sentence. Here's what I mean.

What I want it to be like is this:

I can understand this is impossible for books where the paragraphs are simply longer than the page screen size, but I would love to have it as an option. It just feels so much cleaner and I would improve my reading experience a lot.
