This  component  will  not  appear  in  the  View pane  because  it  will  drop  under  Non-visible
                  components that will show up on the app’s user interface. You can still find it in Components
                  pane and Properties pane.

                  This is the place where we code the components added in the Project Designer window and instruct
                  them the actions to be performed by them. To open Block Editor window, click on Blocks button. And
                  to open Project Designer window, click on Designer button.

                      Built-in Blocks: It contains all the predefined blocks in the application. They are responsible for
                     handling operations like Math, Text, Logic and Control.

                      Component Blocks:  It  contains  relevant  blocks  for  the  components  we  have  added  in  the
                     Design window.
                      Workspace: It arranges all the blocks for coding in the workspace.
                      Trash: It is used for deleting blocks that are not required.

                      Backpack: It stores the copy of all the blocks even when we exit App Inventor.
