 * Navigation buttons
  * Each navigation button should be enabled if and only if there are tabs hidden on its side of the tabbar
  * On left/right navigation button left-click the tabs are shifted in right/left direction with the length of the hidden tab which is about to be displayed. All tabs on the right/left that can not be fully displayed after the shift operation are made hidden
