Github Colon Emoji is a free Chrome extension developed by Adrien Gallou. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

This extension is designed to address a common issue faced by Github users. When typing a colon and pressing enter on Github, it automatically adds the first emoji available. However, in some languages like English, there is no space before a colon unlike in French. This can be frustrating for users who do not want an emoji to be added automatically.

Github Colon Emoji solves this problem by allowing users to press enter just after typing a colon without adding an emoji. To achieve this, users simply need to type at least one character after the colon. This extension provides a convenient solution for those who prefer to control when emojis are added to their Github comments or messages.

With its simple functionality and ease of use, Github Colon Emoji is a valuable tool for Github users who want more control over emoji usage.
