although i have no idea how to make or edit code. i cant imagine that making the screen panels size changeable to be that hard. although i could be wrong
However, you can double the size of the screen (although you won't get more pixels, they'll just be bigger) Assuming you're on Windows,
1. Make a shortcut to the .exe 2. Shortcut > right click > properties 3. Append scale:2 to the end of the text box 4. Open the shortcut. Size should be doubled.
