Thanks for the feedback. It's certainly a challenge to make 1Password work on every website that exists, and even more so to keep it working over time, especially with old items that people created years ago which no longer match the site. We do have a whole "filling and saving" team dedicated to the problem, and we do follow up when users report issues with sites.

I'd love to look into the Quick Access placement. It is supposed to appear on all spaces and sets an NSWindow property to do so. Is there anything particular that you think triggers it (multi-monitor, full screen apps, etc)?
