@leocg I did. The approach is not simple enough and does not want me to prefer Opera to Firefox or Chrome as I need to take some extra steps. In addition, that thread did not help me as only some videos were playing in a higher resolution afterwards but videos outside YouTube not at all. It seems that Opera has too many parts missing in comparison to the mentioned browsers.
If you want a split screen with multiple windows, all you have to do is hit Windows + (arrow key). Eg if you want one window on left and another window on right, Windows + L arrow for one window and Windows + R arrow for the other. That way is so much simpler than this new feature, and the new feature makes the browser unusable for when I want to drag & separate tabs.
@leocg Thanks for replying.
Opera One(version: 115.0.5322.68).
I have now enabled it in settings, which has allowed me to enable it in the sidebar.
Somehow I looked for it in settings several times without finding it.
Apologies and thanks.
Yeah, tab features maybe are good but. Not really understand why there is no possibility to make tabs vertical. This functionality is available in almost every browser including Edge!!!!!
