Anki has https://ankiweb.net/shared/decks

So far I'm really enjoying the geography decks, like https://ankiweb.net/shared/info/2109889812

I'm not a regular user of Anki. But if I start again, how does it work when someone want to upgrade a package to a more recent version ? Does it merge correctly if I have added some cards or added some personal fields to the "Note Types" (and updated some card consequently) ?

I'm still pretty new myself, but I'm pretty sure adding card works but changing fields doesn't.

This support landed late last year as part of https://github.com/ankitects/anki/releases/tag/23.10

> .apkg imports are able to merge changed notetypes, and can exclude scheduling data

I'm the developer of Pine, thanks for sharing! I've actually written a bit about how the whole memory scoring system works here https://pine.substack.com/p/designing-spaced-repetition-syst...

I've wondered a few times about trying to sell a deck for some music theory stuff I want to memorize. Idk how much precedence there is for selling decks but it seems like it could easily be worth $5 or $10 to take the work of deck construction off someone's plate and just let them get cracking on learning it.
