Vivaldi Snapshot 1.6.682.3 marks the beginning of the development of Vivaldi 1.6, the next major version of the popular web browser, and it looks like it has been rebased on Chromium 55.0.2883.64. Besides fixing a bunch of regressions, the new development release implements an option under Settings – Tabs – Tab Features – Tab stacking – Allow Tab Stack Renaming, which lets you rename or name tab stacks. The tab stack naming feature is part of the Vivaldi team’s continued effort on improving tab management for the web browser. Another interesting change that landed in this first Vivaldi 1.6 snapshot is a patch to hide the mouse cursor when watching videos is in full-screen mode, something that users requested for quite some time now.
