What I’m reading here is that it is new for a browser to offer all those features. You’d need to do a bunch of customisation to reach a similar result otherwise. It’s fine that people don’t care about it, but that doesn’t make it less new.

I really like the vertical tabs, the split profiles, the quick notes and the mini windows for links from other applications. If there is a prior product with all these features I’d love to try it. Please send a link.
