The thread about DisplayLink issues after macOS updates really resonates—I've seen how fragile multi-monitor setups can be when a system update breaks drivers. It makes you appreciate tools that visualize complex data clearly. I've been applying a similar idea in my own project, Lifekline (https://lifekline.net/), which charts life fortune trends using K-line graphs based on Chinese Bazi astrology. It's a different domain, but the principle of turning abstract patterns into intuitive visuals is something I find valuable, especially when explaining something as subjective as fortune to users who are new to it.
