GitHub Projects Milestone Progress is a Chrome add-on designed to enhance the project management experience on GitHub. This tool introduces a visual progress bar for milestones, providing an instant overview of project status when milestones are grouped together. The progress bar mirrors the functionality of the new sub-issue feature, making it an intuitive addition for users managing multiple tasks.

The extension is free to use and is particularly useful for teams that handle a significant number of issues within their projects. It supports up to 25 issues per milestone, accommodating GitHub's pagination system. Users can still access progress data for more issues as they scroll down, thanks to its caching feature, ensuring that project tracking remains seamless and efficient.
