Hi! To increase the reliability of Opera lately I've had to lock down V8 optimizer security, adding sites manually one at a time. I’ve taken a similar approach with third-party cookies.
For security settings areas where sites have to be defined one at a time, it would be nice to have a checkbox or toggle to pre-populate the list based on my existing Bookmarks Bar bookmarks (favorites) and/or Speed Dial bookmarks (the icons are the same anyway, right?). This would speed things up a lot, especially when I have to reset Opera when it misbehaves
