Hi all, Gmail is not the only problematic login page, you face same issue on many popular sites (amazon.com, outlook.com, etc). Basically any login page where you get only the password input field.
As suggested by @piejanssens in his feature request post & @jaqxues in their fr post, I feel a simple quick 1 sec toast saying “Autofilled pw for username1” would be mighty helpful.
I could build this toast notification myself & have submitted my post in Github Contributions. If such a feature would be approved, I’d be glad to work on it.
