Innovative? I have been using qutebrowser for a while, and don't see the appeal of this. I just press a binding, start typing the name of the tab (fuzzy), get the list of matches, choose and there I am. As a basic example among many. Nyxt is just as powerful, if not more. If you like visual layouts like the one offered then OK, but not me, I think it's distracting and unnecessary. BTW the headline is blown af
Just because it's not useful or innovative to you, doesn't mean it isn't to others. It's always good to have more players in this game and to me what they are trying to do seems more approachable than the examples you showed.
I agree with your overall points but this but stood out to me because it's not clear if Bonsai uses its own rendering engine of it is just another reskin of Blink / Chromium. What we really need is more competition with browsers which use their own rendering engines. Or at the very least, more browsers using Gecko (Firefox). If this is another Chromium-based browser then it's still definitely good to see some new ideas in UI but we don't really see much other benefit having more players in the game.
What worries me the most is that this is closed source but presented as if it is open source. Their binaries are stored on Github but there's literally nothing in the repo aside a README (https://github.com/hyferg/bonsai-browser-public). This is of particular concern given the sensitive content that people use browsers for these days (banking, shopping, research on potentially sensitive topics, etc). It would be trivial for a malicious browser to do some real damage to people and there's no way to prove this browser's intentions are sincere given how little information (ie "none") is published about its developers or even the code.
