A widget that properly handles twitter feeds, including parsing @username, #hashtag, and URLs into links. It supports displaying profiles images, and even lets you control whether to display the time and date of a tweet or how log ago it happened (about 5 hours ago, etc).

Timeline Twitter Feed let’s you output your timeline feed and multiple hashtags into your WordPress site as flat HTML. 
The output is customizable on nearly every aspect. With or without profile pictures, tweet date, usernames before tweets, hashtags and usernames as links etc. etc. 
CSS styling can be added/overwrited via your theme’s stylesheet or in the Timeline Twitter Feed settings screen. 
There is also a widget to easily add a Twitter feed to your header, sidebar or footer, if your theme supports it.
