For anyone reading through the xkcd archive: I made a tracker extension
I kept losing track of where I was while reading through old xkcd comics, so I made a small Chrome extension for it.
It adds lightweight controls directly on xkcd.com to mark comics as read/unread, favorite them, rate them, and keep a “continue reading” point. There’s also a popup and dashboard for progress, unread ranges, favorites, import/export, etc.
It’s unofficial, not affiliated of course. No account, no analytics, no backend server. The reading data stays in Chrome extension storage.

Mostly sharing because I figured a few other people here might have the same problem.
