Solitaire: * Button assignments: Better layout for ipods, allowing one-handed operation during the game. More logical shortcut buttons for Ondios. Slight changes for other targets, including working button repeat for up/down when there is no dual use. * Help text showing all possible buttons instead of forcing the user to try and find out. The text adapts to LCD resolution and selected font.
