The soon-to-be-released MultiMarkdown Composer actually does something just like this as you type. It highlights reference links that actually point to something, but not those that are just brackets without a definition. As of now, it doesn\'t specifically highlight the \"failed\" links in red, just the \"working\" links. But that could potentially be a feature down the road. --- **Source:** [https://my.remarkbox.com/41a64c95-4208-11e9-9d31-040140774501](https://my.remarkbox.com/41a64c95-4208-11e9-9d31-040140774501) **Snapshot:** 2026-05-05T00:10:24Z **Generator:** Remarkbox `763cacb`
