There was a small formatting issue introduced in Twitter Widget Pro 2.1.0 where there were no spaces between the tweet and meta data or between the date of the tweet and where the tweet was from (such as “from TweetDeck”). When I added the shortcode functionality I had to remove a lot of the excess whitespace so that the formatting built in to WordPress didn’t mess up the formatting of the widget when it was embedded in a post or page. I just released version 2.1.2 that fixed the spacing without messing up the formatting for the shortcodes.
I also added in some links to the WordPress Twitter Widget Pro Support Forum to make it easier for you to ask questions or make suggestions or requests. For more information, go to the Twitter Widget Pro page.
