Save URL in password generation history

Used password generator but forgot to save login/password combo when logging in. When I came back, I couldn’t figure out which generated password had been used. LastPass saves and displays the URL of each generated password.

I’m willing to implement this functionality myself, would a patch for this feature be welcome/do you have any advice?

Where did you find this? When I use LastPass’s menu to generate a password, or look at the history, I don’t see any URLs. The only time LastPass seems to save a URL is when you ask it to add a site.
