Oh, the shock don’t stop there. Just today, I posted a link and someone favored it. Why am I bringing that up? Well, because that seems to be a new feature too. When someone marks a tweet by you as a favorite, it will show up in your Mentions column. As far as I know, that’s all of the new things i spotted in this version.
FYI: If you didn’t know, if you enter a YouTube or Flickr link, it will give you the YouTube/Flickr custom short URL rather than the short URL service you have it set to use.
