(Mind you on mobile I very much don't have a perfectly good window manager, and indeed can't even open multiple instances of most apps…)

But nobody will actually use it the way they describe in this article. Nobody is going to use the site enough to learn and remember to use your site-specific window management when they need it.

Also, I seem to be losing a lot of screen recording for non-bot like traffic. There “not found” message is also not clear why the recording failed.

It would have been much better if they focused on their core product instead of making all these gimmicks.

I prefer the semantics of deep bookmarkable urls to open things in new tabs. HATEOAS! And using my OS tiling to handle things. Choosing my browser/plugins too for better tab management (maybe Arc can help here?)

To note, in the past, this was a big no-no because SEO was important. You had to have good SEO for search engines to index your content efficiently and show up well ranked in search results...

Now, well, that ship has sailed and sank somewhere off the west coast...
