Hello!
I like looking at the “learned items” graph to understand my progress over time.
Since I started learning characters and vocab outside of Hanzi Hero, I skipped a lot of HSK 1 items.
I would like a toggle to allow me to include skipped items in the chart to get a better sense of how many items I know, and how many I have yet to learn (particularly vocab, since that one doesn’t have the HSK progress bars characters have).
