Built persistent text highlighting for ChatGPT

I do a lot of long research sessions in ChatGPT, sometimes 40-60+ messages deep. The problem was always retrieval: useful answers and code snippets got buried, and finding them meant endlessly scrolling back through everything. So I built a simple highlight system into my Chrome extension. How it works: You select any text and press Ctrl+Shift+H. It gets highlighted, saved, and stays there even after refreshes or restarts. There’s also a small navigation bar at the bottom with Previous / Next and a counter, so you can jump between highlights instantly.
