Lost the ability to hid inline menu in Safari in 1Password 8

I had this exact question, and I'm glad I found the answer here. (Apologies for resurrecting an old thread, but it seemed like a better idea than making a brand new, unrelated one.)

Is there any possibility of better integration between the Safari extension prefs and the app prefs? Maybe even a hint in the 1Password app prefs that the extension has its own settings? (Like how the browser's prefs say, "Manage security settings in the 1Password app.")

This was especially confusing to me since the app has a prefs pane called "Browser" — I now realize I assumed that meant there were no other browser extension settings because of that.

I understand that there are probably some technical limitations here, just pointing out that I was also confused between the two.
