ADDITIONAL INFORMATION
The hamburger menu (either left sided or right sided) is present in many kde apps.  it is so consistent that whenever I need to do something not in toolbar I blindly click the menu and generally it is there. The absence of menu in konsole breaks this pattern and it is really frustrating for users. In general the menu should be added to any app that does not have it to complete this pattern, if there is strong reason for some particular app to not do this.
