Google Tests Partial Split View Layout for Chrome OS

According to a new commit of Chromium Gerrit, (spotted by Chrome Story), Google is testing an all-new split-view layout that divides two opened app windows into one-third or two-third layouts, allowing users to get a bigger view of one app and a narrower layout of the other. Google is calling it the Partial Split View.
The feature is currently hidden behind a new flag in Chrome OS. It is worth mentioning that users can already split two app windows into equal parts in Chrome OS. However, the new Partial Split view will put the windows into a new arrangement. Instead of providing a 50-50 layout, the Partial Split divides the windows in a way that glorifies one app over the other. You can check out a preview of the new layout in the mockup attached below.
So, as you can see above, the Partial Split view splits the screen into three parts and assigns two parts to one app window and one part to another. This view would be perfect for situations when you are working on a primary app and need a secondary app, say a to-do list window for reference or any other purpose.
As for its availability, the Partial Split flag has not yet rolled out to any Chrome OS channel. However, we expect it to release in the Canary build of Chrome OS before eventually rolling out to stable users in the coming months. We will update you whenever this feature goes live for all. So stay tuned for further updates, and let us know your thoughts on the new Partial Split feature in the comments below.
