Interesting. I liked the 1Password 6 UI, was frustrated with 1Password 7 and have been loving 1Password 8 so far. Version 7 seemed really clunky when I needed to do certain workflows.
What I dislike about the 7 → 8 transition is that it went from feeling like a handcrafted Mac app to an indistinguishable generic SaaS thing, which is exacerbated by 8 being built with Electron (which brings dozens of little papercuts that are difficult to smooth out, even if the dev cares to try to).
