The GUI was created using PyQT5 (Designer). Using the same tool is important to avoid conflicts with future versions. 

In order to make changes to the GUI, use the following steps:

• Open anaconda prompt 

• Activate your "amigo" environment (More information about environments and anaconda can be found here.)

• Type  "designer" to open the PyQT5 Designer tool

• Use Designer to edit the file ImGUI.ui  and execute the following command to convert the .ui file to a .py file:  pyuic5 -x ImGUI.ui -o ImGUI.py   (IMPORTANT: Do not edit the file ImGUI.py manually !)

Note: Add a custom and meaningful name to EACH element you add to the GUI. If you use a default name, it will create issues when merging the code.
