A simple plugin that allows you to include a Twitter feed on any page or post within your WordPress website. All you need to do is configure the plugin with your Twitter handle and your Twitter access tokens and you are good to go, from there you can include <code>[display_twitter]</code> and the feed will appear.
You can choose how many Tweets will appear, whether to include ReTweets in the list, whether to include replies in the list and whether you want to the Tweets to scroll. Selecting the scroll option will set the Tweets to show in a ‘ticker’ style one after the other automatically.
The plugin is designed to be easily styled, we do not include any default CSS so as not to interfere with the current styling of your site. Each Tweet is a simple <code><li></code> element that can be easily styled.
