No one is asking for that.  But it would be nice if the Help Browser
page for the Limit function made it explicit that if a direction
is not specified, a default direction is used.  Otherwise there
will be people who think that omitting the direction indicates that
a non-directional limit is being requested.

Yes, if one digs into the documentation far enough, the information
is there.  But this is significant enough to merit mention on the
Limit page.

Making the documentation clear is a problem for the designers
of Mathematica.
