Slight mods to TwitterX » http://www.qodo.co.uk/blog/twitterx-a-new-modx-extra-for-pulling-in-twitter-feeds-using-api-1.1/ Added cache_id property to use more than one snippet call on a page. Added toPlaceholder property to display output with custom placeholder. Added support for Twitter favorites timeline. Needs more testing.

 * This uses twitteroauth: https://github.com/abraham/twitteroauth
