I’m really surprised at the level of interest in this feature.
To be honest, I’ve gotten used to using the pinned toolbar icon. Additionally, as a previous LastPass user myself, I can say that having the LastPass overlay icon overlap with a Show Password icon on certain websites was an annoyance, given how reliant I had become on using the overlay icon. But now, given that my behavior has adjusted in accessing Bitwarden without an overlay icon, it’s not really that big of a thing for me. Sure, it would be nice—and it would be one less negative in a direct, new-user comparison with converts from other particular Password Managers. But I wouldn’t call not having it a deal breaker.
