It is nice that Vivaldi has a zoom functionality built in, but it would be much better if the level of zoom was remembered for each url. It is a pain to have to re-zoom to 130% for some pages or 140% for others each time you go there.
The ultimate zoom add-on was NoSquint for Firefox which sadly no longer exists. It not only let you zoom the whole page, or just the text, but also let you darken light text. It has become something of a fad to use low contrast text which is difficult to read under certain lighting conditions.
