1. There no possibility to play in full screen mode. Maybe this is the biggest problem. I can't hide side bar in any way (not not only I)
You can play in full-screen mode just like SwC. All you need to do is activate 'Multi-Window Table Mode'. You will find this option at bottom left on Poker page. After this, game will open in new window (like SwC) and you can maximize the size of window to full screen.
2. Weird mechanic: to see your cards you need to tap on them. On Swcm for example, you see them anytime while you're in game and don't fold.
Cards remain visible as far as you are still in game. They only hide when you fold. Even in that case, you can view by clicking your name.
3. Weird sounds. It's the least problem. Just weird voice. You need at least to add possibility in settings to change voice on sounds.
I found 'check', 'fold', 'call' sound in deep voice weird too.
Also, it doesn't seem relevant why user should listen those voice for his own action. I mean I know I folded, why should sound tell me so. It would be better if those voices are set for other players action not mine.
However, sounds are never the issue if you can simply turn them off from settings. Main issue that I noticed is that player can't see tournament standings while he's playing. Only his present rank is shown on top right which also only show rank out of active players and don't tell how many players actually participated in the tournament.
2. I don't need to tap on my cards to see them, though, that's a weird one for you. Unless you're talking about after you fold, in which case I agree, maybe it should simply show the hand you were dealt in a shaded/greyed out, or near the top line numbers.
I am happy not seeing my cards after I fold. I don't want to repent seeing possible Flush or Straight that I miss after the table cards are dealt.
