At the moment I need a plugin which enables me to create posts from favorited tweets.

I can see, that TB has the ability to create an archive page and to display tweets from selected users and this gave me the idea.

Person X live tweets from an interesting conference which runs for three days - 80 % of his tweets are relevant and 20 % are personal chat. In order to be able to filter out the 20% I choose to mark the 80% as favorites.

So what I suggest is a short code which enables me to create a blog post of tweets based on the following parameters:
1) The feed url for my Twitter Favorites
2) FROM person (optional)
3) FROM time/date (optional)
4) TO time/date (optional)

That way I can create say a seperate blog post per day the conference runs (using FROM and TO time), which only displays those of my favorite tweets that are from person X.

This should of course work in the manner of an archive page, so the content doesn't disappear, when the tweets are no longer on Twitter.
