   As an update, I can see that args[0] holds an obs_data_t object initially (assuming it's settings), but after pushing the button, it's emptied (as well as kwargs).

   What are you trying to do? Have you found a post from @bfxdev about properties ? Maybe this is what are you looking for.
   
   Also a page on the wiki

   The property_modification.py example snippet was written in June 2020, and there was no intention to access settings in callback. They are passed implicitly using star arguments because later you cannot access it ( as you confirmed it ). **kwargs were passed just to make sure nothing breaks.
   Take a look to a new example:

   import obspython as obs
   from itertools import count
   
   G = lambda: ...
   G.settings = None
   G.n = 0
   G.counter = count()
   
   
   def refresh_pressed(props, prop, *args):  # pass settings implicitly
       print("refresh pressed")
       if args:
           G.counter = count(obs.obs_data_get_int(args[0], "saved_int"))
       G.n = next(G.counter)
       p = obs.obs_properties_get(props, "button")
       obs.obs_property_set_description(p, f"refresh pressed {G.n} times")
       return True
   
   
   def script_description():
       return "Modify property and save/load from settings "
   
   
   def script_load(settings):
       G.settings = settings
   
   
   def script_save(settings):
       obs.obs_data_set_int(settings, "saved_int", G.n)
       G.settings = settings
   
   
   def script_properties():
       props = obs.obs_properties_create()
       b = obs.obs_properties_add_button(
           props, "button", "refresh pressed m times", refresh_pressed
       )
       obs.obs_property_set_modified_callback(b, refresh_pressed)
       obs.obs_properties_apply_settings(props, G.settings)
       return props

   In order to access settings in callback they must be global.

   Thank you! On button press, I'm looking to auto-iterate integer counter widgets. Been using the global solution, but seems in script_update I may have been assigning in the wrong direction (settings = G.settings). I'll play some more with it, and if I get it working I'll post my solution...
