SO Dark Chat + is a Chrome extension developed by rlemon that provides a new dark theme for the StackOverflow chat interface. This ongoing development effort is based on the existing se-chat-dark-theme repository on GitHub, but adds additional fixes and features, as well as a few modifications.

One of the main features of SO Dark Chat + is the ability to customize user colors, allowing users to personalize their chat experience. Additionally, the extension includes code highlighting, making it easier for developers to read and understand code snippets shared in the chat.

Another notable feature of SO Dark Chat + is the support for webm/Gifv oneboxing. This means that when a link to a webm or Gifv file is shared in the chat, the extension will display the video directly in the chat window, making it convenient for users to view multimedia content without leaving the chat interface.

Furthermore, SO Dark Chat + includes a code editor, allowing users to write and edit code directly in the chat window. This feature is particularly useful for collaborating on code projects or providing code examples to other users.

Overall, SO Dark Chat + is a valuable extension for StackOverflow chat users who prefer a dark theme and are looking for additional features to enhance their chat experience. With its user color customization, code highlighting, webm/Gifv oneboxing, and code editor, this extension offers a comprehensive solution for those seeking an improved chat interface.
