I think the UI of that feature doesn't look good. The categories aren't listed row-by-row, and it just strikes through the text and the colored boxes don't fill for better visibility.

Are you talking about the "WR progression" graphs?

Yes, WR History

you can find these under the games statistics. note this only check runs that was or is world record that are on speedrun.com (e.g. if a run was a wr on shit like SDA and is not on speedrun.com the run is not going to be there.
