So great to see how much stuff there is going on outside of AI!
I've been working (on and off for over a decade) on a way to manage my unwieldy photo and video collection. I experimented with so many tools before but ultimately nothing ticked all my boxes so I wrote my own. Admittedly lots of niche stuff like proper support for UTC time, stereo photos and partial dates and things like 100% offline face detection and custom tag hierarchies and querying without a database. Each time I add a new feature I'm having a blast :)
