Confirmation to tweet, with option to modify tweet's text

Time to turn off the otherwise charming twitter http://tr.im/wz8y module on our drupal powered site. It encourages twittering private posts.

That was my tweet just now. I love the module and want to have it running on the Kabissa site - but on our site many posts are private and so it makes no sense for the default option to be to tweet them. Perhaps an intermediary step would work - eg "are you sure you wnat to tweet this?" with an option to edit the tweet again to fine tune it before it goes out. Or it needs to be disabled by default, or it needs to recognise that the post is public before tweeting it?

In any case, thanks for the great module - I am looking forward to checking back in later when it matures.

Cheers,

Tobias
