Please add a keystroke to move between suits when playing card games. I don't like searching through a giant listo f cards when I want a specific thing like spades or clubs. Maybe something like shift left and right could be used to move between suits. If you didn't have any cards in a particular suit, the program would report this.

You can use left / right arrow to move between sutes.

This doesn't work. When I press left or right arrow, the current card is repeated.

it repeats the card yes, but it should also move you between sutes. In which game are you trying to do this? I have tried it in Spades and it sure worked there.

It works in Spades. However, it doesn't seem to work in Hearts. This should be a universal feature for all card games.

You are right. Just tried it and it doesn't seem to work in hearts. This does work in most games though, so is probably just an oversight in that game.
Edit: It does actually work, just not during the discard phase. Shouldn't be a big deal.
