When creating Boolean variables, it would be excellent if the value defaulted to true. It would save time!
In my opinion, I use far more Booleans with the value of true than false. It would be relatively no impact on the occasion where one would choose to set it to false. But yes if default of false was wanted then maybe a setting in studio pro to configure the value based on project setting.
It would not save time if you want the variable to be false by default
