This is the browser I've been searching for, it takes the current browser UI/UX paradigms and turns them on their head to use a more contextual computing model and an emphasis on tasks over sites. Add in the command palette and extensive keyboard shortcuts and it's really increasing my productivity in just a short time using it.
It's certainly still early and rough around the edges, I'm very much looking forward to custom search engines, extensions, more minimalist and custom to workspace icons and it will be the only browser I have open. I'm seriously excited about its future!
I also love how responsive the team is, that's a huge benefit!
