Exactly like that. I'm using a laptop with a small screen to build the game and when I test the game out, it's too small to see what's happening. Resizing the window deteriates the sprites. I need the it to zoom in to enlarge the layout or I'll have to enlarge the sprites manually. I have a lot of art, so I cringe at the thought.
Yes! You're a life saver! The pixel art looks great in your example. I like how you used the mouse to resize the screen from 2x to the actual size. That's clever. I'm guessing if I change the mouse function to System>Start & End>On start of layout then this will become the default size? Actually, I going to switch it up and make a keystroke change the size and let the player have that option.
