Many sites allow you to log in with either your email address or username. To do this in LastPass, you have to create two separate entries, one with your username and another with your email address. This causes the two entries to show up in your Security Dashboard under reused passwords. It would be nice to have the option to either link the two entries so that they don't appear as resued... or, better yet, to have the ability to create a single entry that gives you the option to save both the username and email address and then chose between the two when auto-filling your login information.
