Paid Account holders can now view their friends list for a certain day by appending the date to the URL of their friends page: http://exampleusername.livejournal.com/friends/?date=YYYY-MM-DD. This will only show entries from those you currently list as friends, and will order the entries by server time.
EDIT: Editing to add new information. This feature does not work for users who have an S1 layout. Since S1 is no longer supported, developers will evaluate whether it is feasible to make it available in S1.
