Split Screen/side by side

Is an application that allows you to display two things at a time when editing one of them?

I saw the "side by side" app that allows various combinations of screen of split as a document and a pdf file or a web page and an IM app, but it does not allow the display of a thing and the edition of another. ie display a pdf writing and editing a document.

What does anyone know what it is that allows a page split screen display and a pdf and allows the mounting of the doc pages?

There is no split iOS wide screen. If you can have two different applications side by side.

If you want, you will have to rely on a document on the web editor, as the PDF and the document to open in the same application.

You can open a PDF file in a single screen and use Google Docs in the other screen.

BTW. Skipper is also a splitscreenbrowser, but it is free.
