Toggle between open documents in Adobe app...?

Hi

I'm working with the app on my tablet and wanted to know whether there's an option for a quick toggle between two or more open documents, similar to the tabs on Win/Mac? For example, when I'm reading an academic book and need to toggle to another one quickly, I need to go back and open the other file. I know there aren't any windows in tablets, but can I do something like this in the app?

Thanks!
