Rumba provides two different versions of the user interface. You can switch between these at any time according to your personal
               preferences.

- Ribbon
                  
               
- Originally introduced by Microsoft Office 2007, this interface organizes commands into a ‘ribbon’ across the top of the application
                  window. The commands shown change according to the tab that has been selected. This makes application features easier to find
                  and quicker to use.
