Is there any way to close Opera PC version with closing last tab? I haven't found any such option in opera://flags so far...

Thanks lando. Hopefully those two features will be implemented soon. I really don't need those two features. As I remember well tab menu removal option was present in some of the previous Opera versions but they removed it.
Do you have any news about home button? I haven't checked threads regarding that matter.

Is there any way to remove tab menu in the upper right corner of the browser, as well as to remove + button on the left side of the bookmarks bar?
There were some tutorials about removing tab menu but they're not working in newer versions of Opera.
