i think there should be ILs for the indivisual tracks using the time given when we do time trials. I hope they get added

You'll love http://mariokartplayers.com/mk8/ then.

http://mkwrs.com is a very good place to look at all the current world records, as well as previous records for all the main Mario kart games.

I know there are other websites as well that do something similar for people who Don't have a top 10 place, so it seems pretty redundant to add ILs to any MK leaderboard.

Not really a reason to add something that already exists on other websites. We'll keep it as it is right now.
