I came to ask where the base definitions were stored so I could edit them, thanks for posting this. Gotta make the code completions match my own peculiarities >.<

If I messed something up in my own version of the file, I can just delete it from the folder and restart the application right?

I would also really like this feature. But thank you Rui for pointing out that I can just use terminal to make a new file in my current project folder. It's an obvious solution that I hadn't thought of. I currently use Textastic and terminal split screen side by side. My M2 Air can do 100 char on terminal and a little over 100 on Textastic with the sidebar closed.
