Opera.ini settings
This is an exhaustive list of all the preferences that can be changed in the current Devices CDK version.
Note: A change of Opera's preferences during runtime will not necessarily have a direct effect on the running instance. It may be necessary to reload the current document, open a new window, or restart Opera. Most preferences related to layout have this delay.
