Haven't played poker in many years, just wanted to play some zoom hands but I was surprised to see the interface is even worse than it was back then.
By far the most annoying thing is when you click on "Fast Fold" and around that time the hand is folded to you the button turns into "Fold" so it doesn't register the click.
When playing multiple tables, the focus thingy doesn't really work and buttons on tables which are out of focus will sometimes not register and you have to click twice or even multiple times. Really annoying since it sometimes works, sometimes it doesn't and there's the risk of getting auto-folded in a pot I had interest in.
Then there's the issue of seeing the mucked hand of an opponent. I get it, he mucked his hand so I can't see it right away. But I can't see it even when I click on the hand history, I have to replay the hand and I only see it when the replay is over. Maybe I'm missing something here, it's too ridiculous to work like that.
