in vivaldi you can ctrl-d to bookmark then shift-tab to set a shortcut name
in future you can just ctrl-t then shortcut name to go straight to bookmark.
yeah, it's bookmarks under the hood, but being able to just go 'ctrl-t' then 'webmail' or 'workmail' or whatever saves the convolutions of smartcomplete and autocomplete and displaying history or suggestions and such in the url bar.
