Where is the Twitter section?
Originally, GIFwrapped shipped with support for a GIF-only Twitter feed. This completely broke when Twitter introduced "native" GIF support late-2014. This is because a large portion of GIFs in people's timelines were now videos. Because of all this, I made the difficult decision to cut the Twitter section altogether, which happened in version 1.1.
The good news is that version 1.5 introduced the ability to save GIFs directly from Twitter, converting the video format back to a loveable old GIF in the process. You can find more detail on how to use this feature in the article about saving GIFs from Twitter.
