What is the reason for screen.widgets removed?

[tsingwang]

In my opinion, screen.widgets is useful. Example:

"""Refresh widgets in current screen only."""
for widget in self.screen.widgets:
    widget.do_custom_refresh()

At this point there is no need to focus on background screen widgets.

You can do for widget in self.screen.query("*") to get all widgets.
