... Hence this feature request... which has already been added to the list, so there's not much need to discuss whether or not it's valuable or not. I understand that it is.
Aha - this discussion led me to another way of meeting this need, that might be easier to code,
and more pleasing to use.
On the Alt-` Master Password Prompt window, display the results of encrypting the empty
string using the entered master password.
Then each time I entered my Master Password, I'd glance at the encryption of the empty
string, to be sure it came up as I expected.
This would really confuse someone looking over my shoulder. They'd see me type one
thing, see a password-like word cycle through variations as I type, and the asterisks in
the actual web form would be hiding an entirely different string, that incorporated the URL.
