Works as of 2025-10-10! I feel like I've definitely been memorizing kanji at least partially by the specific fonts, so this is a helpful way to make sure you learn kanji even if they don't look 1:1 the same as before.

Some way to (arguably?) improve this extension:
1. Add an option to select which fonts are used (=checklist with tickboxes of available fonts?), in case you really don't want one of them to show up (or just want to use a few of them).
2. Show somewhere which font is being displayed currently? (I really like some of these and would like to use them for other purposes, but I'd have to track down what the fonts are called.)
3. An option to change the font for every review item, as opposed to every review session?

Even without these features, it's definitely a handy tool that I'll keep using. Thanks!
