1. Optimized the initialization process. Now when initialization is interrupted, the program will exit faster and will not do too much loading (including playing sound effects and displaying) 2. Optimized the core functions of form creation and modification. Window positions (initialization) on screen are now more accurate, and switching between window sizes and positions is faster and smoother 3. Optimized the logical sequence of drawing images and resizing when switching windows, and now the window image display changes more smoothly when switching window sizes
