Coming back to this topic after I got a message that Anki 2.0 will stop being synced to AnkiWeb as of January 1, 2020. The only reason I’m still using Anki 2.0 is the other Anki plugin which allows me to track studied time instead of progress.
So far any plans for implementing raw counts (cards/day or minutes/day) for your plugin, @bluetulip?
