Have had Zen in my browser collection for a while. On my Mac it's a secondary browser and it's my primary elsewhere.

It's picked up all the most important parts of Arc's design while leaving behind the bits that were questionable (such as TBC's decision to not have bookmarks) and at this point it's pretty solid.

I had been continuing to use Arc for the odd site that insists on something Chromium-based (usually without good reason) since it's the only chromeclone that feels somewhat at home on macOS and hasn't succumb to an ugly generic flat look. It'll be missed.
