I've been using PhpStorm for three plus years and it never stops asking me to add to git. I never want to add to git, ever.
I have changed it to never ask so many times I am tired of saying no and changing settings. I have my settings synced but still "do you want to add this file to git?"... No I do not! I never did and I never will! I will handle git outside of the IDE and never use PHPStorm for this so please stop doing this!
How the hell do you stop it asking to add to git and make it permanent like forever and ever and ever and never ask me again because I do not want it to add my new file to git because I told it NO over and over and over again.
