No mac version of the software ;_;
That's not surprising, though =/
Also, during ESA2, I noticed that a window with a sum up of the player locations in the previous rounds would be useful.
The problem was that I had to swap some players in the second round of pools and in the bracket. And since it was a big tournament, I couldn't remember who was in which pool and coming from where. So first, I had some problems with the seeding TIO made for second pools (i.e. 2 of the few English guys in the same second pool), and then I also had some problems while swapping players myself, because I had to check if they weren't in the same pool before. It lead to some awkward poules, and it was even worse for the bracket.
My idea is something like that :

With this kind of thing, the one in charge of the seeding could easily see that this pool sucks because of me, as I was already in pool 8 with PC in the previous round, and that I'm with another Frenchie. I think adding such thing in the pool assignment viewer would be really useful and would make seeding preparation easier and faster.
Doing the same thing for the bracket would be cool, too, but it seems to be much more complex to add it.
