Work on Vivaldi 1.13 started two months ago, on September 21, 2017, and since then the web browser received no less than eleven snapshots that brought all the goodies listed at a glance in the next paragraphs. This release is built on top of the latest Chromium 62 open-source web browser and it’s the first of many to come to rely more on built-in functionality than add-ons. Highlights of Vivaldi 1.13 include a new window panel that promises to give users more control over their tabs and helps them manage multiple tabs at once more easily. As you can see in the video attached below, the window panel opens a tree-style view of your tabs on the side of the browser’s window, but for now it only works per window.
