I liked "Note" and it's right click option to to send selected text to "Note". I liked having the quick access bar to History, Bookmarks, Notes. I liked the right click encyclopedia and dictionary option (after people here told me how to get it to stop accessing Russian versions and source English language (but never again shall I go to so much trouble)). I'm finding password manager is inconsistent in offering the option to save them.
In summary I'm finding that the reasons I liked Opera are no longer there. I may go back to the older version I was using - I'd done a complete uninstall because it had been getting slow and difficult - too much of the time responding with Not Responding. But it may be time for me to move on and try something else.
