It'd be very beneficial to show Show number of matched logins on the 1Password icon (both extension icon and the icon on form fields).
It is very helpful to see if I already have login items on a web page or not. In this way, I'd go to the registration page of the website directly without any click/shortcut.
It can be an optional setting if you think it may be confusing for some.
