Chrome just updated and in the "What's New" page they are promoting a split screen option.
View two pages in one tab Split view puts two pages side-by-side in the same tab so you can easily compare options, watch a video while taking notes, and more.
Ways to open a split view:
Drag another tab or link to the left or right edge of your browser window.
You can also right-click a link and select Open link in split view.
