I feel like there's a big issue with the undoing of the close all tabs button. If you just accidentally close all tabs (like I did) since it's really easy to, you might not see the undo button since you're not going to immediately look back at the button that closed all the tabs. And if you accidentally open another tab? There goes everything.
I believe there should be an "Undo close all tabs" button in the new tab plus menu, so that even after the undo button in the tab sidebar goes away, you still get a chance later on to restore the tabs, instead of letting the tabs just be gone forever.
i just lost so many tabs because of this and theres nothing i can do about it because i opened another tab without knowing beforehand that just makes it impossible to get the tabs back
