I am planning to reduce my games. Now I have about 45 games in progress. I want to reduce that to around 30.

When I see My Current Tournaments, I see that I advanced in some tournaments, but I'm not sure which ones. I must click them one by one to see in what tournaments I'm still competing. Perhaps it would be a an option to see in which tournament I'm still competing or waiting when the next round starts.

I agree, saem counts for the team matches. You have to click all the groups and then all the team matches one by one to see if you have subscibed.

So... you should be able to see if you are already subsribed on a tournament, and you must see in "My Current Tournaments" if you are still competing a tournament or eliminated.
