Incremental link search
As an old Opera 12 user I got used to the handy pair of incremental searches: [ul] [li]regular incremental search[/li] [li]incremental link search[/li] [/ul] I hereby add my vote for including the incremental link search to Vivaldi! I believe I used that feature more than I used the back button in Opera: jumping into news stories, google hits, API reference docs, etc.
Agreed, I often use the "," (comma) key to do the incremental link search in O12. One of the best features in my opinion! Saves a lot
