I had this small idea for a while now. Increase or make the hand for hand alert bigger. It would definitely speed up the game as those few players who max-tank fold each hand don't get to see it, but rather get dealt into a new hand.
I understand that having to code some sort of an alert that pops up in the middle of the window takes a lot of hours and there are more pressing issues to be dealt with. In my oppinion, at least changing the current green collor to white, making the alert stay on for the duration of Hand-for-hand (like the break message) would improve the hand for hand period in tournaments (especially in those that go through this phase with 2-3 tables).
