goldendict-ng/src/mainwindow.cc
Konstantin Isakov e13a4596ae + Dictionary bar, a bar with dictonary icons for the current group, was
implemented. Clicking icons disables corresponding dictionaries. When
  clicking with Shift/Ctrl, a dictionary can be made solo.
  The feature is currently only available in main window only, scan popup
  will be addressed later.
+ 'View' menu introduced. It allows switching toolbars and side pane on/off
  without any arcane knowledge on how to toggle them on/off via RMB.
