Show HN: Waypoint.nvim – A Neovim plugin for bookmarking lines of code I made this plugin because I felt like existing bookmark plugins were lacking some important features, including:<p>- The ability to reorder your bookmarks<p>- The ability to delete and move your bookmarks in bulk<p>- The ability to view lines of code around your bookmarks<p>- Syntax highlighting in the preview window<p>- Resilience to the content of files changing (e.g. checking out a git commit that changes the file contents won&#x27;t delete your bookmarks)<p>Let me know what you think! If you have any feedback, please create a github issue or email patricksharp.dev@gmail.com

Build to test Cloudflare workers and their infra along with deck.gl performance that is incredible in my opinion.
