Public service announcement: You can now use the 'reload' button without having to save the generator first (amazing and groundbreaking)
Note that the 'auto' checkbox doesn't actually clear variables - it just fully re-executes all the square/curly blocks in the HTML. So if you're doing stuff where your code needs variables to be "cleared"/fresh before the first generation, then you'll have noticed that you actually need to click the 'reload' button (or refresh the whole browser tab) to get your generator back to a completely "fresh" state. But, as the annoying message would inform you, clicking the reload button required saving your generator first. That's not required any more. I should have fixed this about 6 years ago. Took about 15 mins π
