Hi Kaj,
the browser back/forward buttons let you move through the history of the visited pages. This works when you move for example between the main playback screen and the Settings page, because they have different urls.
But it does not work when you want to move through the many screens of the same main playback section, because those actions are rendered through Javascript and you are staying on the same page (and obviously same url).
So we suggest to avoid using back/forward browser buttons and possibly get rid of them
enabling the full screen mode.
