This is a chromium special, thousands of people have been asking for this since 2011, on forums, stackoverflow, reddit, etc...
Problem is, many users have a Lot of favorites, and don't usually clean browser history, and then what happens? Every time you type anything in the address bar, you get bombarded by urls you don't want to show up, there's also the privacy and performance points, Firefox and Vivaldi (also chromium based) have implemented this option.
Besides this forum and the feedback button on OperaGX, is there any other place I can give this feedback? This forum is only read by the moderators responding question and nothing gets tracked.
