= Analysis =
== Overview ==
Develop additional features defined in [wiki:OPEN_BOOKS_TABBAR_R0#Overview], including:
 * Navigation buttons when the tabbar is too short to display all tabs.
 * Tabbar context menus.

== Task requirements ==
 * Create the context menu when right-clicked on a tab.
 * Create additional menu items to the context menu when right-clicked on the tabbar area.
 * Implement the Cascade and Tile functionality.
 * Highlight active tab.
 * Implement the navigation buttons and their appearance/disappearance.
 * Left-click on a book's tab button should restore the book window if it had been minimized.

== Task result ==
The result of this task is source code. 

== Implementation idea ==
 * Navigation buttons - the funtionality should be similar to the tabbar navigation behaviour of most browsers (e.g. check IE6, Mozilla Firefox 3).
  * Each navigation button should be enabled if and only if there are tabs hidden (or partially visible) on its side of the tabbar.
  * On left/right navigation button left-click the tabs should be shifted in right/left direction with the length of the hidden tab which is about to be displayed (including the left and right margins).
  * After the shift operation the last tab on the right/left is allowed to be partially displayed. After that the desired behaviour is:
   * For the next shift operation in the opposite direction (left/right) the shift length should be the one of the hidden part of the tab (including the right/left margin).
   * If the partially displayed tab is clicked, a new shift operation should be initiated to display the whole tab.
 * Tabbar context menus should be as specified in [wiki:OPEN_BOOKS_TABBAR_R0#Implementationidea] with the addition of "Tile Horizontally" and "Tile Vertically" menu items instead of the "Tile" item.

 * Could you please add to this task that clicking a book's tab button should restore the book window?  i.e. if the window is minimized, it should expand it, or restore the state. - sriggins
