Two more best features for Tabs

Hi,
I've tried Opera both when they were using their own engine and after they switched to Chromium, but I stopped using it because now it's purchased by a Chinese company and it's no longer the old Opera.
to me it's a bloated browser, they want to win the market by making weird features, like gaming browser or features like this.

duplicate tab detection - do you often open duplicate tabs in your browser? if yes why?
I for one don't, maybe 1 in 100000 times I open a duplicate tab by Mistake which I immediately close myself.
that feature would be useless for me.

CTRL + Tab preview - it's kinda useless too the way I see it.
remember I'm not saying your post is useless, I'm talking about features that Opera developers put into their browser.
it's useless because Opera already has tab previews, so there doesn't need to be 2 kinds of previews.
Edge is getting Tab previews too, soon. and once that happens which will hopefully be like Edge classic, you will be able to see contents of each tab without even lifting your hand from your mouse, clicking on mouse buttons nor touching your keyboard.
