Closing Grasshopper Check

I’m working on a particular type of component for GH, but it causes significant headaches if I forget to toggle a boolean value to false when closing - does GH offer any check if its closing that I can automatically convert the value to false?

No, Just lock your definition before saving or use the False Start Toggle from @andheum
