Vertical Twitch is a free Chrome add-on developed by A7med.me that allows users to watch Twitch streams with the chat displayed below the video in a vertical orientation. With this add-on, you have the ability to resize the video and chat windows to suit your preferences.

In addition to the vertical orientation feature, Vertical Twitch also provides the option to view your Twitch following list and receive notifications when your favorite streamers go live. This convenient add-on eliminates the need to open multiple tabs or windows to view the stream and chat separately.

Version 2.4 of Vertical Twitch includes minor fixes to enhance the user experience. Previous versions have also introduced features like the ability to open streams directly on Twitch.tv, fix for VT icon on Twitch.tv, and support for Twitch OAuth API.

Overall, Vertical Twitch is a useful add-on for Twitch enthusiasts who prefer a vertical layout for their streams and chat, providing a seamless viewing experience.
