Please, please, please allow to remove this awful button. Keeping track of all the tabs is one of the main purposes of the browser - and Opera is not doing a great job. I also lose my tabs all the time. Why you do this to me? And ctrl+shift+T only re-opens like 15 of them? Whyyyyy? I really need them all.
Honestly, who would ever want to use this button anyway? Just close them all through some safe option in a menu if you need to. But why place it so close to "close tabs to the right"? This is simply cruel, why, whyyyy?
