@leocg yes @leocg is right. I use old button for 2 reasons.
1, more then 10 tabs
2, sync via cloud with my personal computer, corporate computer etc.
I don't need to search between tabs, I don't need to search the content of all pages. when i need to find something, i need to find it on one page.
why make it so complicated. just return the opera://flags/#search-in-open-tabs, or make button... and give the user a choice ... i dont know, mayby is new button for someone usefull... it would be a win on both sides ...
or just make a button to turn off automatic updates and everyone would be happy. no one would download the new version and everyone would stay with 69
