I do wish Bitwarden had this feature, although I do find that using the toolbar instead is not inconvenient. I have also come across times when the LastPass overlay icon clashed with a Show Password toggle.
With regard to the discussion about “old” vs “new” users—with all due respect, I think there are people on both sides of it that are being opinionated.
When people use a particular software, they develop likes and dislikes about it. It is not unfair for people to criticize a product for not having benefits they enjoyed with its competitor. Additionally, I don’t think mocking people because “using the toolbar is too hard” adds to the discussion. It’s not that it’s too hard—it’s just markedly not as convenient for them. Berating people for requesting this is like berating someone for complaining that their previous car had volume controls on the steering wheel, which they used a lot, but the new one doesn’t. “Why don’t you just use the knob on the dash?!” you would say. That doesn’t further the discussion.
On the other hand, I wouldn’t classify not having this feature as a “deal breaker.” If there are problems using Bitwarden with certain websites, I would consider that a website-design flaw. And I do think getting upset that this feature isn’t implemented is making it a more serious issue than it needs to be.
