• Increased the default Chat window size to better accommodate the conversation list.
• Increased the Music Player default height so playback controls remain visible.
• Adjusted the Tic-Tac-Toe default window height so lower controls are not clipped.
• Adjusted the 2048 default window height so the game content is fully visible on initial open.
