I am trying to reload a scripted python extension with multiple .py files. Some of them are located in subfolders, see below for example.

extension\_name/  
├── service/  
│ ├── logic.py  
│ └── gui.py  
└── extension\_name.py

It seems that 3DSlicer only reloads the extension\_name.py file. Is this the expected behavior when reloading extensions? Or do I need to specify explicitly which files should be reloaded additionally?
