Hey there I have a suggestion about rolling a winner for the raffle.
I have had the issue a couple of time when tabbing in or out games sometimes didn't work perfectly and when I pressed enter or spacebar
it would reroll a second, or even a third winner. This is quite awkward if you roll unintentionally two or three winners.
So my suggestion would be a optional 'reroll lock', enabled by default, of a minute and if one presses roll again it would get a confirm message if the streamer wants to reroll.
The confirmation dialog box should be defaulted to NO so pressing by accident spacebar/enter or even when your mouse button is faulty and click twice (yes I have had such a mouse) it would never reroll a winner.
