2. Player 2
   The view of player 2 is placed at the right side of the game view normally.

5. Gaming table
   The gaming table in the center of the game view shows the played cards, the Talon, and the most important data of the current game. At the bottom left of the table, the action advice for the activated player is show. If the current system user controls the player, an additional action box is shown beneath in some cases. With this, the user can select actions or announcements.
    
6. App bar
   The app bar provides access to common application tasks, such as reverting an unwanted action or displaying help info. It can either occupy a fixed space above the gaming table or overlay the gaming table at the top border. In the later case, it is translucent and the overlaid part of the gaming table is still visible therefore. Additionally, it's visibility can be toggled in this case by clicking on a free space of the game view. If the local option "Auto hide app bar" is selected, the unfixed app bar is automatically hidden when the system user's player is deactivated.

   If there are bystanders while playing online, their portraits are displayed from left to right in the app bar. A bystander portrait can be clicked on by an activated player to switch places with the bystander or to have the bystander replace him or her as a player and session participant. But the bystander himself can also click on his portrait to change himself to a player when a seat is free.
