the picture posted by zorglub-fr shows how the old Opera looked like and some things are impossible to find in the new Opera :
- the scrolling menu for the bookmarks (as seen on the picture)
- the little key for the password, as you can see in this picture : http://nsa38.casimages.com/img/2015/05/18//150518031701816792.jpg
These 2 things were very useful and I really would like to have it in the new Opera.
