Very often, if autofill fails due to a variety of reasons, I have to go to the extension to copy and paste the username and password. I am coming over from 1password, and this is a small, but noticable QOL feature they have. If I open the extension, type in a website, I can copy the username, go to paste it, reopen the extension, and the login is still there so I can easily copy the password.
In bitwarden, I have to open the extension, type in the website, copy the username. Then when I go back, I have to retype the website to copy the password.
If it would just remember where it was for 30 seconds, it would be a huge quality of life improvement in my opinion.
