The /whois/ command gives the profile of a user as expected, but it
neglects to state whether that user follows me & also neglects to
disclose whether I am following that other account. It would be *very*
useful if that information were included in the whois output. It’s the
most basic info you generally want to know when visiting a profile.

Apart from the /whois/ command (which operates on one account at a
time), it would also be very useful to query for the whole list of
accounts who follow me and accounts I am following.

One use-case (apart from account migration) is follow reciprocity. If
someone follows me, I look at their timeline. If a substantial portion
of their posts are in a language I understand and the content is
generally acceptible, I follow back. If I do not follow back
(e.g. they have no timeline at the time), it would be useful to
periodically examine the asymetric follow cases and re-review whether
to follow or unfollow.
