With the latest Google Chrome update you can save and open tab groups across desktop devices when you need them. This makes it easier to clean up your tab strip and focus on the thing you need to get done, right now.
Right-click a Tab and select Add tab to group.
Turn on Save group and your group will appear in the bookmarks bar.
To remove the group from your tab strip but keep it for later, right-click the group header and select Hide.
On a different desktop device, sign-in and see your groups in the bookmark bar.
Tip: In the tab strip, click the group header to collapse the group.
