Widget for "View conversation" instead of Search Widget: will it be implemented in near future?


I want to show twitter’s conversation of several people at my site.
I mean conversation like original twitter.com site shows link “View conversation”. When I press this link and I show aquestion of some follower and answer tweet’s author.

I’m trying to use search widget with string like "to:someone OR from:someone"
But I can’t use it at real site because author’s tweets go first in time line and other people’s questions follows after the oldest author’s tweet.
It looks tangled and unattractive indeed.

Why developers doesn’t offer a normal widget to view CONVERSATION of people in concordance with time line like the twitter site shows it?
Are there some plans to make such a widget?
