FEATURE REQUEST: Split-Screen capabilities on OS X 10.11 El Capitan
Since the OS X 10.11 El Capitan update rolled out, one of the major features is split-screen. Split-screen allows you to run two apps side by side in fullscreen mode. Currently, this doesn't work with Vivaldi. It would be nice if it did. I think this would allow power users on OS X 10.11 El Capitan to work and browse more productively.
