Hi Chris,
While preparing for the next gen Firmware, maybe it is not too late to re-ask this:
There's 3 types of pages: Dashboard, Mediaplayer, and Settings.
On Mediaplayer, you show a Dashboard-button. On Dashboard you show the Mediaplayer-button. And then suddenly, on Settings-pages you show a Back-button. Media-player and Dashboard button obviously are direct and very clear. Back-button though is somewhat different. It isn't very clear in its destination. Also, if one would want to go to the Mediaplayer from the Settings page, one would need to go to the Dashboard first, and then click the Mediaplayer-button.
Why don't you just show Dashboard and Mediaplayer on all Settings-pages? I know it's no big deal, but if one seeks to cut out unnecessary clicks or buttons, this could be one of them: Take out 'Back' , and only show Dashboard or Mediaplayer.
Should be very easy, doesn't take any resources (BDP-1 importance), and doesn't cost any extra screen real estate, even on mobile devices.
One would only have to remember that for Settings, one needs to go to the Dashboard first, but that seems quite logical...
Cheers,
Marius
