advent+- is a free Chrome extension developed by mdwhatcott that aims to enhance the navigation experience on the Advent of Code website. This extension modifies the puzzle titles by adding hyperlinks to the previous and next day puzzles, making it easier for users to navigate through the challenges.

When using advent+-, the leading and trailing dash padding `---` in the puzzle titles are replaced with hyperlinks. For example, a puzzle title like "--- Day 16: Aunt Sue ---" will be transformed into "[--] Day 16: Aunt Sue [++]", with the `[--]` and `[++]` serving as hyperlinks to the Day 15 and Day 17 puzzles, respectively.

With advent+-, users can quickly jump to the previous or next puzzle without having to manually navigate through the Advent of Code website. This simple yet effective enhancement saves time and improves the overall user experience.

advent+- is available as a Chrome extension and can be easily installed from the Chrome Web Store. It is a handy tool for those participating in the Advent of Code challenge and looking for a convenient way to navigate between puzzles.

Note: advent+- is an open-source project, and its source code can be found on GitHub for those interested in exploring or contributing to the development.
