Hi,
I'm afraid you are mistaking this for another app, this is the Home Poker Tournament Manager (HPTM), not Poker Watch.
The first one I could do, but would that be a cheering sound or rather a mocking one? Or is it meant to inform all the tables that someone left?
The HPTM does not display currency because that is irrelevant, you'll most likely be using whatever currency your country uses during your home game, so no need to display that.
The HPTM currently does not keep track of who is participating in the game. That might indeed be an interesting addition, however it's a lot of work and hard to scale for all possible sizes of home games.
The question is also: how could we display all this information in a meaningful way on the screen? Would there be a list with participants on the screen with their points? That would clutter the current screen too much in my opinion.
