Comment 7 for bug 1451999

While the header allows a maximum of 3 actions. The 3rd header action is a menu button which shows other actions defined. So it would be necessary to move the grid/list view to the settings page.

So here is more or less the final layout that I have in mind,
- 3 tabs (Podcasts, Episodes, Settings)
- Podcasts tab will have 2 header buttons (Add new podcast and search)
- Episodes Page will use the new header sections to provide 3 different views (downloaded, what's new and favourites)
- Header actions in the episodes page will be based on the view..for instance the what's new view will show a "Download all" and "Mark all viewed" header action and so on.
- Episode Queue will be implemented similar to the music app

It would be nice to use the swipe gesture to show/hide the bottom bar but let's revisit this later as there is a lot of other work to be done.
