With more and more sites offering Two Factor Authentication, it would be handy to somehow in LastPass be able to track which sites one has enabled 2FA for and which type of 2FA. Even if it is something that could be entered manually by the user that would be a useful feature, but of course if it could be detected automatically that would be even better, but I can imagine that's not so easy.
The 2FA coverage could also potentially be made part of the overall security score (in addition to measuring the password security which makes up most of the score).
