Feature request: navigating docs in portrait mode

In portrait mode, it would be great to be able to browse between documents instead of having to return to the dropdown menu - really slows down doc browsing. Any plans for a feature like this in future upgrades?

BTW i’m overjoyed to have my docs from DTP on my iPad - thanks so much for the app.

UPDATE: I noticed in landscape that the doc list is available. Would it be possible to add a next/previous arrow when reading docs in portrait?
