In Gin Rummy, you can now click the "sort" button to sort your cards from left to right or vice versa, by rank.
|The sort button toggles between ">" and "<"|
Also in Gin Rummy, when you pick a card, it will get added to the right of your hand. This suggestion was made by someone who uses the site on a tablet. It's easier to move a card when you can grab the entire thing and not just an edge. I hope this change won't disturb others too much. I usually dislike making changes to the user interface, but I think the pluses outweigh the minuses, in this case.
[Edit: I see only negative comments below... is there anyone who uses a tablet and likes the new placement that puts your picked card to the right? Feedback from all is welcome!]
