Although the new hotkey will be great I will still use password auto-populate to save time as thats the way I browse most of the time.
I have noticed a possible feature request that could be handy.
On many forums their is a user config page which allows you to change your passwords, avatars, sigs, contacts, options etc.
I have noticed that auto-populate puts in a value for "Password" "New Password" and "Confirm Password"
I would like to suggest that autofill should work if it detects "Password" but if it sees "New Password" on a page it shouldn't auto-populate any fields. Or better yet a user definable "But not if you see this:" exception.
