I will explain through an example. I come to whole chapter page from Genesis 17:1. I am on whole chapter page, and I want to see parallel Bible translations (Serbian, Hungarian, English, other translations...) for Genesis 17:7. Long press to verse 17:7 and from context menu I go direct to the parallel Bible translations for Genesis 17:7.
In the whole chapter window you can already double-tap (or triple-tap depending on your settings) to switch between the parallel translations. It is not likely I will add a button to do this sorry.
I see. You want to close the fullscreen Chapter Window and return to the Parallel view, with that verse open.
