GUI Scaler Mod automatically changes your menu sizes to fit your screen perfectly. It watches how big your game window is and makes the buttons, inventory, and text larger or smaller so you can always read them clearly. This saves you from constantly opening the settings menu to fix the size yourself when you play on different monitors or switch in and out of fullscreen mode.
