Proposed Changes

In the plugin development section, it is not documented how a plugin should access its own settings.

from django.conf import settings

settings.PLUGINS_CONFIG['plugin_name']['settings_key']

This method works and is Django standard, but NetBox populates the dict with the defaults from the plugin configuration.

I think this should be documented.

Maybe it makes sense to provide a helper utility and document its use instead? That might be a bit cleaner for developers, and provide a hook layer for potential future use. Something like:

from extras.plugins import get_plugin_config

myvar = get_plugin_config('plugin_name', 'myvar')

I think an associated templatetag might also be wise.
