docs: Some ideas for your widget:
          - Textual information (alert, license place number)
          - Check boxes : if checked, send e-mail to your mom when the analyzer spots something
          - .. or send an sms to yourself
          - You can include the cv2.imshow window to the widget to see how the analyzer proceeds
