What happens if you put all your browser tabs in two dimensions?
Answer: you get a mess.
That's why browsers weren't built like that, and also why I think this will not work.
But happy to be proven wrong of course.
What if... imagine stacked skewed windows and you scrolled through them like a rolladex

But people frequently go out of their way to put their tabs into two dimensions.
There are tab trees: https://chromewebstore.google.com/detail/tabtree/afejdkkhibi...
There are tab groups: https://support.mozilla.org/en-US/kb/tab-groups
There are tab containers: https://addons.mozilla.org/en-US/firefox/addon/multi-account...
It seems pretty clear that people want their tabs to be organized in multiple dimensions.
