Add-on development Question

Can’t properly formulate google search, so ask here…
While developing add-ons -> do some changes in text.py file -> Ctrl+S -> then hit F8(reload scripts) in blender -> see the changes.
But this way don’t work for me when add-on is not a single file.py, but a folder with init.py and other add-on’s files. It only helps to restart blender every time.
Any solution?
