It should also go without saying, but I will say it anyway for completeness, that such top sites shouldn't include advertisements. To see a list of the websites you have visited today, click Today on the. It goes without saying that any such analysis would need to be machine-local and not query a 3rd party API to determine which sites should be 'top', to avoid privacy concerns. These can be a combination of sites sorted by the number of visits they have had, or outliers that the browser thinks you may wish to re-visit (I'm not entirely sure how Firefox's highlights work). Other browsers like Firefox and Chrome will show on the start page frequently visited sites, 'top sites', highlights etc. This isn't so much a feature request that I would want, but I notice that for other users to whom I may want to recommend Vivaldi, such a feature may be missed.
