I pushed a lot of changes to the branch and I think most things are working now for basic usage. Of course may design points are not implemented yet. Would be nice, if somebody could lead me to a developer, that could possibly assess the effort for the previously mentioned mixed poster layout.

• Show title flags also in wall view (besides episodes)
  
• Added genre menagement: Genre images in widgets and IconsWall views, settings also added to switch back to icons
  
• New progress bar for poster and thumbnail views (within poster as overlay)
  
• Changed Episode list item view in widget
  
• Added support for helptext (can be deactivated in settings, helptexts to be extended/fixed)
  
• Added additional footer information in home (Artists, Title, Year, ...)
  
• Show title and year in footer for media items in wall view (500) because of missing details panel
  
• Fixed views for MyPrograms, Pictures, AddonBrowser, MyPVRChannels
  
• Larger channel logos with 21:9 support behind channel number
  
• New icons for player control buttons
  
• Fix for wrong focus when navigation back to home screen from any other screen
